I have a 2005 Chrysler Town and Country.  The power locks stopped working yesterday.  All other electrical systems seem fine.  I could not locate any blown fuses.  When researching this problem, I also checked for Dodge Caravan reports.  I found a mention of a potential BCM power locks failure detection if it thinks a lock is frozen or otherwise would overload the drive motor.  I disconnected my battery for 20 minutes to reset the BCM.  When I reconnected my battery the power locks worked just fine.

I had the same issue on my 2005 Town and Country.  I followed Joe Wilson's advice and it worked perfectly.  Thank you for the info.

Thanks for your help with my folks' 2005 Grand Caravan power locks and electronic keys. Neither option for locking/opening the doors would work, and the only entry/lock-up was manual and by standard key on the driver's side.

  They may not have closed the tail gate completely on a long trip and the BCM must've gotten the idea they had a failure of one of the door locks. By the time they got to our place hours later, it was a complete puzzle.

  I googled and came up with your comments. Voila! Everything works after disconnecting the battery and letting it sit.

I tried the same thing on my 2005 Town and Country and it worked perfectly. Thanks for saving me a ton of money at the dealer!

We also have a 2005 T&C with the same issue - the power locks do not work as described.  You can temporarily fix this by disconnecting the positive side of the battery for ~5 minutes, however the length of time that the locks work will vary.  We have ~44k miles on the van.  It is an interesting problem that is very frustrating.


Bill wrote at 2007-08-02 16:37:04
I had the same trouble and was able to fix it very simply.  The electronics apparently had stored a bit in the wrong place.  I simply removed the IOD fuse for about ten seconds and replaced it.  This apparently reset whatever piece of electronics was confused.  



The IOD fuse is in the fuse box under the hood by the left front fender and is the fuse furthest to the front and left.  I think IOD is something like Ignition Off Drain (power for the stuff that needs power when the key is off).



That worked for me.  Hope it is the same issue for you.

I recently purchased a 2005 T&C and the power door locks quit working. After reading various answers on several message boards I removed the 20A fuse marked IOD for 30 seconds. After replacing the fuse everything seemed to work okay. The key to know wether or not you've performed the reset is to note the time display on the radio, it should read 12:00. This saved me a day long trip to the dealer.

I have had the same problem on my 2005 T&C Touring. I disconnected the battery for 24 hours, and the problem went away. 2 days later the problem came back. I am bringing the van back to the dealership to have it checked out.

I have an issue with the Power door locks on my 2005 Dodge Caravan.This vehicle had an aftermarket keyless entry that started acting up so I removed it from the vehicle and ever since the doors will not lock with the Power door button when the door or doors are open (I have to get in,shut the door and then lock the doors with the Power door button open the door manually push the door button down then shut the door) to lock the vehicle. The Power button will unlock the doors when the door is open it just wont lock them when it is open. I removed th IOD Fuse and reset the electronics, this fixed my problem for now. If problem returns I will update to let every one know. Thanks for saving me time and MONEY!

I have a 2005 Grand Caravan and removing the IOD fuse for 30 seconds works great too!  Thank you!


Tckgator wrote at 2007-09-13 15:23:58
I also tried resetting the system by removing the IOD fuse and also disconnecting the battery.  This does solve the problem but only for about a week.  The dealer found a TRB on it, but wants an hour of labor to reflash the computer and won't guarantee that it will solve the problem.  The service manager also said he had not heard of the problem.  I told him to do a quick search on the internet it is all over the place.


Roger wrote at 2007-09-16 00:57:13
Thanks for the info! Removing the IOD fuse in my 2005 Grand Caravan reset the locks immediately. I only waited a few seconds before putting it back in, but that was enough to do the trick.


Bryan wrote at 2007-09-16 23:01:46
The info on the IOD fuse was great! It worked like a charm. Thanks for preventing me from an expensive trip to the mechanics.


Jeanne Morales wrote at 2007-09-22 23:31:52
Thank you so much for sharing this solution.

I had to talk to 2 service managers and they did not have a clue and wanted me to bring the van in.

Fortunately I have a younger co-worker that suggested I go online to see about others with this problem.

I am sure this solution saved me money and lots of time.




Sharon wrote at 2007-09-25 17:23:52
Awesome-I thought I would spend all day and money at the dealer to fix my problem.  Instead, I read this forum, popped out the IOD fuse for about 10 seconds, popped it back in, and presto bingo, the locks work again.  Thanks so much for sharing your experiences!   I AM A HAPPY CAMPER!


Shelly wrote at 2007-10-04 20:12:13
This is FYI to Roland and Donald.  I had the same problem with 2005 Town and Country door locks.  I "jiggled" the wires under dash on driver side and it corrected the problem.


Romott wrote at 2007-10-05 18:54:00
I had the same problem with my 2005 T&C.  I pulled the IOD fuse for 30 seconds and replaced it. FIXED!  Takes longer to reset the clock!



Sounds like bad programming that should be corrected free of charge by Chrysler.

I had the same problem with my 2005 Grand Caravan.  Removing the Pos on the battery or removing the IOD fuse(much easier) will work to reset your computer.   This problem kept re-occurring which was frustrating but I found that the keyed driver door lock wasn't operating freely.  It could have been preventing the power door lock from locking or unlocking which would cause the computer to lock the system out.  A little WD40 and it hasn't happened since.


Franklin wrote at 2007-10-13 21:15:45
I work at a dealership and this works! Our service manager was prepared to initiate a lemon law return on a 2005 T&C because it could not be repaired until I printed this page and made him read it.  Needless to say problem solved!

The IOD fuse worked for me too. Just removed and replaced - no waiting. Door locks now work again - hope it lasts...


Danny Kuiper, Jr. wrote at 2007-10-20 02:25:24
Just did this with my '05 Grand Caravan.  Worked perfectly.  Also listened carefully to the lock movement and it sounds like the driver side sliding doors lock is dragging.  Going to see if the problem reoccurs then I'm working on that door next.  Thanks for the help everyone.


J wrote at 2007-10-28 15:30:40
Yep! IOD fuse worked. However check the condition of your doors key lock. Ours was deformed and a scratch was on the casing. Apparently some goof tried to break into our van.


SarasotaFrank wrote at 2007-12-09 19:04:29
Took car (05 T&C) to dealer for 2 factory recall fixes.  Never had a door lock problem prior.  Two days later I had the door lock problem, Back to dealer who charged $75 and said his diagostics equipment reset the computer.  Two days later problem again.  Dealer said Master Control Module bad. He ordered, I waited two more days, took back and total bill close to $400. I called and wrote Chrysler customer service. They eventually agreed to reimburse me $250 (took 3 months to get the check). No problem for these past 4 months or so until today.  I googled and found this forum and did the IOD fuse thing...  Door locks work fine now.  I wonder how long this will last.  There is a electrical design bug somewhere... Bottom line, it is over 10 miles to dealership and the minimum is a half-day shot to hell.  This forum saved my a 20 mile round-trip and at least a half-day of life.  I am so grateful to all of you.  Thanks

My wife told me the doors would no longer lock in our 2005 Grand Caravan. I thought OH, OH, how much is that going to COST?

So I went to a repair shop to see if they knew of a quick fix. "Bring it by in the morning and leave it for a few hours", they said. "The last one we FIXED we had to take off the whole dash panel to find the problem", they said. Well when I got home I did a google search and found this site, followed the suggestions found here and disconnected the battery, removed the 20 amp IOD fuse and put every thing back. Then I used the remote and it locked the doors.

IT WORKS AGAIN!  THANK YOU VERY MUCH! Won't be going by that shop tomorrow, or any other time in the future.

My 2005 Grand Caravan power locks  quit working, and after reading numerous articles on the internet, I pulled the IOD fuse for a few seconds, then replaced it, and the locks were back to normal.  It looks like another fine engineering job by Chrysler.  Thank God for the

internet!

Thanks very very very much. I own a 2005 Chrysler t & C. Removed the 20 AMP IOD fuse for 30 seconds and the locks started working like magic.

Same problem exactly.  2005 T&C power door locks stopped working but we pulled the IOD fuse for a minute, put it baqck and the locks are working again.  Thanks so much for everyones input - you're all awesome!


MKWOOD wrote at 2008-02-16 17:28:57
Seems like most of the notes here regard 2005 models so I figured I'd add that the same issue and fix worked for my 2007 Town & Country.  Yet another reason why I like my last van better, but at least this fix was free.  Thanks to all the responders who make this Internet resource work!


Tom R wrote at 2008-02-16 19:30:53
Just removed the IOD fuse. Locks worked right away. I don't know how long it will last, but it works right now. Thanks for the help

My 2005 Town & Country has the same problem with the locks.  Pulling the fuse and putting it back in works, but never for long.  Glad to see these posts.  I was about to take it to the dealer, but it looks like that would be a waste of time and money.

I have the same issue with my 2005 Dodge Caravan and my 2005 Chrysler Town & Country. I have to remove the fuse at least once a week though, it doesn't seem to last. Finally after about 6 months of removing the fuse on e of my door lock just completely quit working and now I haven't had to remove the fuse for about 3 weeks. Chrysler doesn't care about this problem, I called and they told me to take it to a dealer and oh it isn't free, you have to pay to get it fixed. Fortunately the Dodge Caravan was still under Warranty. Thanks for the info, I am glad I found this site.


Scotty wrote at 2008-04-22 20:31:20
Very well said! Went in slip the IOD fuse and I got my power locks back. The dealer said they had to rewire my door or had a loose wire. Dealers in my opinion have MECHANICS that don't always know there work. Saved me $250.00 or more. Thank You

Same locks problem with my Town and Country. I noticed the button on the electric door wasn't working this morning, and then found out none of the electronic locks would work, including the key fob and door lock. Googled first, thank goodness, and tried the 30 second fuse removal. It didn't work, even though it did reset the time on the radio. Tried it again, and left the fuse out for about 5 minutes. Worked like a charm. Thanks!


Susan Coulange wrote at 2008-05-17 18:22:20
My 2005 Town and Country had the same problem: power door locks that quit working. As I was searching for which replacement part I needed, I happened upon this blog. We immediately disconnect the battery and IOP fuse and low, and behold: It worked! We forgot IT's first response to all computer problems: Reboot!  Thanks to everyone for saving us time and money.

Buckster wrote at 2008-05-27 02:45:36
I have had the same problem with the front passenger power window stop operating, only later to fix itself. Recently all the door locks stopped operating as described above. I disconnected the battery and reconnected it. Everything worked fine for a while. Don't buy all new harnesses and guess. I believe there is a computer issue here as after the battery was reconnected, everything worked. The more I read, this is definately a Chrysler issue that is a larger problem then just us.


D wrote at 2008-06-07 02:46:39
Great solution, you made me look great.  Wife had me work on her friends 2005 Chrysler minvan.  This solution worked  great, pull IOD fuse, took longer to put it back.  I did find out later the friend who is very short has a strap hanging from the back door that she uses to pull the door down, then throws the other end inside which I can tell gets caught in the latch.  Thanks D


steve wrote at 2008-08-02 17:58:40
If it is just the locks not locking/unlocking from the fob or door switches, there is a TSB to flash the body control software.  Until you get that applied, try pulling the IOM fuse (front most, drivers side of fuse block under hood), inspect fuse, count to 10, reinstall.  That resets the software.  The doors are different circuits from the locks so that's a seperate issue.


bondrdm wrote at 2008-08-11 03:04:52
It's been 3 months with the problem and I'm getting tired of pulling the fuse every two days.  Dealer has no idea.


Jay from FL wrote at 2008-08-29 04:02:02
Thanks for this tip! We bought a 2005 T&C yesterday and it stopped working last night! I spent half a day at the dealership today. They fixed it and it worked exactly twice. Just tried the IOD trick and it worked right away!


Rik wrote at 2008-09-14 18:59:24
I just have to chime and and say thank you so much for this.  It's posts like this one that remind me how cool the internet is!  I was pretty worried that I'd have to spend an arm and a leg for some guy to take 15 minutes tinkering about under the hood... and then I found this.  It worked like a charm.  I unhooked the battery for about 10 minutes (checked the tire pressure while I was waiting), hooked it back up and all was well.  Thanks again!

I recently brought my DGCV back to Japan (military) and I just experienced this same problem.  The locks worked yesterday, but its  raining now and this seems to be a common factor.  Its still raining, so I really don't want to open the hood and reset this fuse.  I am very excited to see if this will work.  If it does, everyone on numerous Blogs have saved me a lot of money.  The Japanese Crysler Dealer would probably sick it to me.  This is such a disappointment with Dodge.


Ray wrote at 2008-12-20 21:45:49
If your power door locks are having a problem locking with the Key Fob or the door lock switch inside the vehicle the problem is most likely the fuse. The front left hand fuse, 20Amp, called the IDO fuse, which is marked on the inside of the fuse door, under the hood, sometime becomes corroded and is not making good contact, simply pull this fuse and re-install it, that should solve you problem. If the fuse if broken replace it.


ddujin wrote at 2009-01-06 21:16:57
Simple  open  fuse box, and take out  one in left bottom  place (my is  yellow), wipe  it  and  return back. That  is  all



Thanks


jrprich wrote at 2009-01-27 00:50:22
Well I just pulled the IOD fuse for 30 sec......and I am amazed that the locks seem to work now !!!!



Took me awhile to find the IOD fuse as I thought it would be a 20 amp......but only 10 amp on the 99 and hidden way up in a corner.



Hope this works, I will visit the dealer tomorrow and try again to get a FOB programmed.



THANKS TO ALL

Have 2005 T&C.  We've been pulling the IOD about every 2 months for the last 8 months.  Now it doesn't last for more than 2 days.  Took to dealer and they have no idea.  Going to try jiggling the wires under the dash and putting WD40 in the key lock as mentioned in other responses here to see if that works.  I will let you know.


Laurrie wrote at 2009-02-27 18:37:53

Removing and replacing IOD fuse Worked like a charm. I just spent 2 hours at a shop (TG for free) and they didn't find the problem. Finding this site was a blessing. BTW, I have a 2005 T&C. It looks like this year is a bad one for Door locks!

Well, on my van I don't have the power sliding doors.  But my locks and key less entry wouldn't work.  I was told to reset the battery for a few  minutes and it worked on my wife's van.


bpos wrote at 2009-07-05 23:16:27
My 2005 T&C has the same problem of power door lock/unlock not working.  It has only 44,000 miles. I took it to the dealer and he said he reprogrammed the BCM.  After that it worked for a few hours and then the same problem.  He charged me about $55 for this.  I went to him again and he said he will have to replace the BCM which will cost about $700 (BCM + labor).  I am going to try the IOD fuse disconnect and battery disconnect method and hope it will work.  Thank You every body if this works.

THANKS Chrysler T&C Owners. You just saved me $500 the dealer wanted for a new BCM.Pulled the IOD fuse for 10 minutes and reinstalled and THE DOOR LOCKS WORK AGAIN!!!! Ran and got the wife, it's her car, and she is happy again. Going to see the dealer Monday for a heart to heart talk!!!

You people rock!!!  My 05 Town and Country's door locks (by key or by button on the door) stopped working.... I took out the IOD fuse, counted to ten, reinstalled and they work again.  Van has been awesome other than this one issue.


Jason 'vanRijn' Kasper wrote at 2009-08-31 00:50:45
Yeah, I'm having this problem too. 2005 Chrysler, Town & Country. I've been doing the "take the IOD fuse out for 5 minutes until the radio gets reset to 12:00, put it back in again" thing for a couple of weeks now and it only seems to fix it for a day. With all of the people who were saying that this fixed things for them, I was really hopeful that it would for me too. I'm just wondering how many people who tried this and had it work eventually had it stop "working" and what they did to actually fix it? Do I really have to take my T&C into the dealer? Is there something simple (like spray WD-40 somewhere or something) to fix the underlying problem? What I'm worried about most is taking the car into the dealer, having them do something to reset whatever it is that keeps disabling my power locks, and then have the problem come right back again. Grrr, this is really annoying!


anna wrote at 2009-09-07 19:18:43
thank God for the internet and this site... i umplugged the fuse it now it works...Yah! hopefully it will last but i rather unplug the fuse everyday than pay $500... thanks again


Rich wrote at 2009-09-29 17:38:36
The IOD Fuse removal works only for a couple of days. I've been doing it now for 3 months. The dealer said they need to reprogram the BCM. I will wait until I see other hints from this forum.


Brian wrote at 2009-10-20 20:24:05
I had to go to Chyrsler dealer and update software and since then it worked fine.  You can pull the IOD fuse but you might have to do it every other day.


Barry wrote at 2010-04-22 18:44:02
Late addition to this post.. my 2005 T&C had the following issue(s)

Driver side door lock would work to 'unlock' but not lock. Passenger side was ok.  The key FOB worked ok as well. The interesting item to note was that my switches for the power windows would trigger the door lock's.  Tried the IOD reset and that cleared the window switches issue but driver side door switch still works only for open not close.  Will check that out for connectivity or bad switch.  Thanks much for the posts, really appreciate the info.


chintu wrote at 2010-06-08 00:19:47
looks like this is a big problem? look how many people are having this issue. I think this is high time Chysler should recall and fix this issue. what do you think?


rbrown30 wrote at 2010-06-23 20:52:22
My experience with this is: when locks (all of them) cease to work, removing the fuse or battery cable for 5-10 minutes will restore function. However it may work once, twice, ten times or more and fail again. Note: if the car is locked, it has always unlocked with the remote before it ceases to function again.

My internet research has not found a permenant fix and given the age of the vehicles and that it is not what Chrysler and the Feds consider a safety issue, no recall or correction out of warranty.


Alan wrote at 2010-07-19 13:53:15
Same problem here, same solution with our 2005 T&C.  The reason I'm posting is just to let folks know that for us at least, the problem has recurred only about once a year.  Fingers crossed.

Well THANK YOU ALL SOOOO MUCH..I am SOOOO glad I searched this 1st before taking ours to the garage..we were on vacation and my niece had hit the slide door on the van..we all went inside the store and when we came out the door was opened and I thought omg it probably burnt something up because it will keep shutting over and over if something is keeping it from closing..anyways it was after that that my power door locks didnt work anymore..the hatch did but the 2 front and both slides didnt..so after I told my husband what I read here..we tried and YAYYYYYY it worked..that saved us a ton of $$$ at the garage..because I called them today and they were like well we have no idea and it will take some time to figure out what is wrong and would have to charge us to just see whats wrong and then we would have to pay to have it fixed..so once again THANK YOU SO MUCH!!! ;)

We are new to this problem and have re-set the fuse, but the problem resurfaces every week or two.  If anyone has a permanent fix, please post it so that we can all learn from you.  Thanks!


Thecia wrote at 2010-09-28 03:07:11
I just wanted to let everyone know that we had this lock problem too. Where the power door locks would not work either by using the key fob or the interior lock/unlock buttons. And the initial solution is to pull the IOD fuse as previously mentioned. But after doing this if you want it to last as a long term solution you cannot use the interior door buttons to lock or unlock. ONLY use the KEY FOB and you shouldn't have anymore problems. We used to have this happen from daily to several times a week. But I read somewhere else not to use the interior car lock/unlock buttons and stopped doing so and it has been 2 years without the lock problem happening again.  


Gene wrote at 2010-10-02 01:16:52
I just purchased a 2005 Town and Country and have been having the same problem.  This has to justify a recall.  I have tried the IOD fuse thing at least once a day since I purchased the vehicle.  Very frustrating.  There has to be a solution.  If I find it I'll post it here.  Thanks for all your posts.  They have at least given a temporary solution.

Check it out!!! My passenger side window stopped working about 2 months ago. I thought it was a fuse, which I could not find! Then my driver side window stopped today. Instead of going to the dealer to be "ripped off", I read this website and found the answer. Hold down the window switch and hit the inside of the bottom door panel! Worked like a charm on both windows!! Thanks for the teamwork!


Doyle wrote at 2010-11-05 18:00:36
Thank you, Thank you. Pulled the IOD fuse and worked. I had just paid a mechanic $85 to reset the comp. and it lasted about 2 weeks, so if I can do it myself that is awesome.  I do think a recall is in order. A lot of us are having the same problem.

Hi everyone. I have the same problem with my grand caravan 2005. Fuse work for me fine. But in a week that happened again. I am a little be electronic technician and i think its time to replace the battery. When the battery is old and don't have a to much power like new one , and when you starting the engine starter drain the all power to start engine in this time the board computer lost the power for the few millisecond and getting stuck that why you have to reset it. This is just theory not verified

Just read all you guys posts. I took that little fuse out and put it right back in now its working fine. Thank you to all of you. Internet rocks!!!!!, But after this, I will not buy another american made car.


sandy c wrote at 2011-07-16 18:54:22
I had the same problem, we did the battery and it only work for a minute. We did the battery again and did the IOD, and it works great. I work for a GM dealership, and asked the service manager, he never got back to me. Thank you for all your help.


Wendy wrote at 2011-07-18 07:36:48
I had the same problem as many others with my door locks that completely quit working on my 2005 T&C. I pulled the IOD fuse and it worked for about 1 week. After the third time pulling it, it got to be something you have to do every time you want to lock the doors and even then it wasn't consistent. I finally had to take it in to the dealer - they charged me a hour's labor at $100+ to "flash" the computer. Of course, the first time it quit working again after a day, so I took it right back the next day to the dealer and dealt directly with the service manager. He told me Dodge/Chrysler would not do a recall (he apparently has dealt with this exact problem in over 100 vans) despite the obvious flaw. It ended up taking over an hour for the techs to get the reprogramming to "take" on my van's computer, but since then I've not had another problem. I think it is total BS that Chrysler won't fix this with a recall - it's a potential safety issue! If you can't lock your doors any weirdo at a stoplight can just open your doors and come on it! I WILL NOT be buying another MOPAR product after this.

Thanks for the posts on this. Disconnecting the battery did the trick. With this number of common issues, Chrysler should be recalling. Just one more reason added to a long list of why I will never purchase another Chrysler. American jobs aside, I would like to see this company go bye bye!

Sometimes the computer needs to be reset.  Do this by carefully removing the positive battery lead for about 5 minutes.  Don't short the positive terminal to any other metal by touching the wrench to metal and the positive terminal at the same time.  After 5 mins, reconnect the positive battery terminal wire.  



Doing this resets all codes and software.  You'l find the power locks will work after doing this.  Not sure if doing this will help with the other symptoms.

Thanks for the help. 2005 T/C door locks were not working until I tried the "re-boot" approach (battery disconnect for 10 sec).

I am sure glad I went online to read all your remarks. I have the same problem with my 2005 Town & Country (Door Locks on all four doors will not respond to remote control. Tail lift, however, can be opened and closed with remote control. I pulled out the BOD fuse, wait a minute, and then put it back.

Every thing now works like a charm (all four door locks now respond to remote control. Again, thanks for the postings. It saved me a trip to the dealer ($$$$$).

Beauty!  Pulled the IOD fuse for 20 seconds, everything is working again perfectly.  God bless the interwebz :)

After the door locks quit, I went to a service station to checkfuses--no problem.  But during about a 2 month period three batteries--Advanced Auto - died--each time they replaced the battery and immedately the locke began to work properly.  This week it started again, but the baterry checked good as did the alternator.  I saw to day the "disconect" solution for the battery and the locks work now.



I talked to the service man at the Crysler dealer, and two other mechanics--never heard of it.

On most vehicles removing the iod fuse will only be a temporary fix to a long term problem. If the power locks on your vehicle are not working properly there is likely something that is causing the problem. One of the posts here suggested a tailgate that was not closed properly or all the way, or a lock tumbler that has been tampered with or broken into. To fix this first remove the iod fuse wait 20 seconds then replace. Try the locks and see if they work if they do not you will need to have the lock system on your vehicle serviced. If this works this will only be a temporary fix on most vehicles. Next disconnect the negative battery cable (Black) wait 10 seconds then touch the negative battery cable end to the positive battery cable end (Red) this will remove an residual energy left in the system thus causing the system to restart or reboot. As the the system reboots all sensors in the vehicle thus re-calibrating the lock postition or tailgate postiton. If this does not work most likely you are gonna need a new body control module (BCM) wich is not cheap. Good luck hope this post along with the others helps everyone.

I had this problem for months I kept taken out the BCM fuse and reset everything then my dash lights and gauges started flickering and become erratic. I replaced the battery and alternator and this did not help. I read were someone replaced the battery terminal. I took my apart and clean them and put ignition and battery sealer on them. Its been about 6 months and no problems with door locks or gauges.

Had my 2005 T&C passenger window fail right after serious storm. No blown fues.  Tried the IOD method mentioned above.  Worked perfectly.  Thanks

I have a 2005 T&C and the locks stopped working 9 months ago.  Finally got off my butt and looked it up.  Read this answer and went out to check.  I will say that the labels under the cover are very confusing.  I selected and pulled the wrong fuse at first.  Frustrated I looked on the cover again but it really didn't help.  If you look down on the fuses you'll see a 20amp fuse marked "IOD" next to the correct fuse.  I pulled/checked it.  It was good.  Replaced it then check my doors.  Had to dance a jig I was so happy.  This answer is really good.  Now let's see how long this will last.
