Auto Air Conditioning & Heater Repair/Toyota Sienna compressor failure


Zac wrote at 2007-07-26 19:22:51
Have the EXACT same going on today, this very moment.  I have 2,800 miles over warranty (38,800), but neither the dealership nor Toyota corporate customer service will offer any assistance.

Issue: Bearing broke in compressor and damaged the condenser.

Cost: $3,400.

Me? I've owned four Toyotas: Camry; Land Cruiser; Avalon; Sienna.  All bought at Toyota dealerships.

Toyota corp. told me "We don't buy business."

Toyota dealership told me that I don't have a service history with them.  (The reason? I just moved to town)

EXTREMELY disappointed.  Toyota just lost a customer.

I owned a 2004 Sienna which had  among  several problems one major problerm related to the A/C. The dealer had worked on the problem for at least one year.

The compressor was relaced--to no avail- I was put in a rental car for three weeks. A dye was injected into the system to locate leaks. To no avail. Various other items were inspected and replaced. To no avail. Freon replaced several times. To no avail. Now the utter seriousness of the problem surfaced in that me the driver and passengers were becoming drowsy  while onboard. In one case eye problems surfaced. At low speed conditions worsened. I suspect due to lesser fresh air intake. After two years  of no repair and no other options offered I was forced to get rid of the Sienna. Glad I was not offered another one.

I have a 2004 Sienna Van and this is the SECOND condenser that has failed!!! The first was under warranty, and now the second one is way past my warranty.  My quote was $2800.  Ridiculous!  I bought a Toyota becuase of its reliability, how wrong I was!!!

I am sitting at a Toyota Service center at this exact moment with this problem. Have an 2004 Sienna XLE Limited with 58k miles. AC quit working yesterday. Dealer told me that entire AC system was shot and needs replacing. $3526 to fix, about 10% of the new purchase price and 20-25% of the present worth. I balked at the price. They showed me the TSB on the AC system to prove that only a Toyota Deler could fix it. Right now they have a call with the Area Director to see if Toyota will cover the cost of the parts and I'll pay labor.

Let you know how that works out.

Dear Al..owner of 2004 Toyota Sienna..I wish I could read your feedback from Director of Toyota Cooperate. I am experiencing the same problem with my 2004 van at 67K miles I lost a/c...they said it was the compressor at 68K I have no a/c at all and told "I" need to have compressor clutch/coil fixed at a cost to me for parts and reduced labor fees ($70.00 from $92.50/hr) they are blaming it on the Maine winters and "crap" getting under the hood!! I am so upset with Toyota..I have seen numerous complaints for same problem with AC and when I asked about the TSB they said that was for their knowledge to help the technician, not a recall! How awful of Toyota to not stand by their minivan! I have been a loyal customer for 4 years and have serviced this vehicle as recommended. I am supposed to go back Monday for a repair that will cost me over $500 and 2 1/2 hours of waiting time. Never mind that I have been there 2 days this week for over 5 hours while they so say "fixed" the a/c one day only to fail that afternoon and couldn't "fix it" today!!! I wish the Better Business Bureau would help customers with todays economic times who can afford to pay over $1500 dollars in service like I have in 4 months. I will not be buying a Toyota in the future...they are showing they do not stand by their customer when a costly repair needs fixing. Good Luck Al!!!!!

THANK YOU FOR YOUR REPLY!!!!  We just had our 05 Sienna XLE Compressor/Clutch go out.  And in the heat of Southern California we also found out that there is a national backorder of the parts so our local dealer (Quality Toyota) can't fix the problem for 2-3 weeks.  Great news huh?  Thanks for the additional information about the Service Bulletin.  I complained about 2 years ago about the air being wierd and I wonder if it's somewher in my notes through my service guy.  Would this hold up to the case if I noticed problems with the air back then?  I am hoping that I won't have to pay for this new system even though my minivan too doesn't fall under the warranty (it's at 60K miles and a little over 3 years old).

Off to take care of our little newborn (another reason I need AC asap).

I guess I got a few extra miles out of my 2004 Sienna XLE in N. Bay Area, CA before this design flaw manifested itself in my vehicle. I am at 68K miles and the quote to fix is $4,809! One reason I spent so much more for the Toyota minivan is for vehicle reliability. Really disappointed... not sure what we will do.

Pam wrote at 2009-07-22 20:52:18
Just had the same issue, one week before leaving for vacation 12 hr drive away with two small kids.  Needless to say we had to get it fixed in a hurry and had to pay the price. Though we got it fixed at half the price from Tuffy instead of the dealer. Toyota dealer denied a technical service bulletin (TSB)out there or that other people were having the same issue. Of course our van was out of the 3 yr 36k mile warrenty. But Tuffy gave us a copy of the TSB when we got it fixed.  Researched on the web and found tons of others with the same issue.  Don't know that this helps but you are definitely not the only one experiencing the issue.

July 23, 2009-My ac went out and I am at 140,000 miles. I guess I am lucky. I forgot, my ac went out last year and I choose not to get it repaired. Now it is too hot and I got it repaired by someone other than the dealer. The dealer quoted me a cost of$3,400.00 including labor. I was able to get Nu's Auto Body and Repair to fix it at $688.00. They replaced the ac compressor with a new Denso, flushed the condensor, put a new receiver dryer on and flush out the expansion valves. My clutch on the ac compressor stopped working. I had cold air,it just worked intermittently. I have always bought Toyotas and my next car was going to be a Toyota Highlander. Now I think I will buy Hondas. This problem appears to be a recall item that needs to be addressed. I have loved owning a Toyota. I will miss not purchasing another one.

Comment from Carlsbad, CA:  On July 15, 2009 I had a "catastrophic" compressor failure on my 2004 Sienna LE/AWD.  The car has approximately 93,000 and has been perfect, up to this point.  The local dealer quoted >$4,300.00 to replace entire system because of fine metal particles throughout.  The service writer said there are TSBs for the AC compressor in this model.  There are no preventive maintenance remedies.  It can happen at any time.  Check other similar forums.  It seems to be a problem that is happening more than Toyota wants to admit.

I have a 2004 sienna 68k miles and I have read the reports because I have the same problem.The AC unit stopped working two days ago 5/2/10.I can't see paying ($4000.00)for something that is clearly a recall due to all the other sienna owners AC problems I'm writing this just to put my sienna on the list.

I am the owner of a 2004 Sienna XLE Limited w/ 73k miles and have recently experienced A/C failures. It first started about 3 months ago with sporadic warm air while the A/C was on. Then it left a mildew smell and shortly thereafter was followed by no cold air whatsoever. I took it to the Autoport(military base auto repair) and they couldn't figure out the problem after two days of troubleshooting. They finally called me today and said it would cost me $1250 for a new compressor, dryer, and labor of course. I feel lucky in a way that it's not as expensive as some other "victims", but with two little kids and living in Hawaii I don't have much of a choice in getting this matter fixed. Hopefully this will be the end of the problem as I am not made of money and could simply not afford any more repairs for our only vehicle. I replaced the radiator last summer as well, got a pretty decent price on it when I bought it used. I am a Toyota fan, but this is my first Toyota and it might be my last if it continues to give me problems. Cars are so darn expensive, and I don't even want a luxurious ride, just a safe and dependable one. Wish Toyota would send a rebate check to all registered 2004 Sienna owners to cover the cost of their lack of quality.

Plalo wrote at 2010-07-22 20:39:20
Unbelievable how prominent this problem is. Add my 2004 to the list at around 72k miles. Of course we were on the way to the beach in this killer heat in the NE right now. Luckily my littlest is 4 yr. old and just whined for 3 hours. If I had an infant the service manager's head would be rolling right now. Has anybody had any luck with restitution from Toyota on this clear oversight on quality?  Anybody suggest a reliable replacement brand besides the costly OEM? Good luck to all and thanks in advance for any replies.  

Matt wrote at 2010-07-30 13:13:08
Add mine to the list.   Intermittent hot air coming from the Air conditioning.  My (non dealer) shop will replace with a non OEM compressor ($480).  He also tells me the radiator is leaking !

Having the same problem right now with my 2004 sienna XLE.  They recharged it for $115 after my 20% coupon and it still didn't work.  Estimated cost is $2000 to fix.  Funny thing is that it works fine when it's cool out, but won't kick on when it's really hot (in the 90's)  I started to smell something today that I described as wet dog smell.

I'm not fixing it, I'm just getting a new car instead.

Logging in as another victim.  From the state of Kentucky where the Sienna's are built !  

2004 Sienna LE, 72,953 miles.  

On a website called I read one entry that Toyota doubled the warranty on the AC unit for 2004-2005 Siennas.  I mentioned this to my service guy at the Toyota dealer and he had no information about that.  He didn't even know about the TSB AC003-05 which was put in place to prevent catastrophic failure.  Like all of you I went with Toyota based upon their reliability and Consumers's Reports recommendations.  I guess only people with positive experiences answer their customer surveys.  Tomorrow will determine is Toyota stands by their reputation or I drive over to the Honda dealer and take what I can get on a Sienna without AC in trade for a Honda Odessy

Lt Col Marc wrote at 2010-08-20 01:19:18
Has any one presented this problem to the Attorney General in the state? I juts had my 2004 Sienna XLE blow out and expect it to cost close to $3000. I asked the dealer to have the Toyota regional mgr look into and advise what Toyota will/can do. It's apparent from all the comments that this is a technical problem that is the responsibilty of Toyota. Has anyone talked to an attorney? Do any of you feel that this could become a class action? I am not an attorney, just retired Army.

Mark in KC wrote at 2010-08-31 18:44:35
Our 2004 Sienna has 92K miles and we have had the same issues.  Compressor, Clutch, everything needs to be replaced (metal was everywhere) and the cost was close to $4K. We went to a non-dealer and he is doing the job for $1,500. We asked Toyota to help and they said no. This is after we spent $1,500 earlier this summer on the rear a/c.  I was looking to get a new Sienna soon, but now we are open to anything but a Toyota.

Our 2004 Sienna has just 50K miles.  We are the original owners and it is spotless.  We live in Nevada so it doesn't see rain or snow.  Our AC first went out in late 2007.  Luckily we had the extracare warranty so that 4 grand belongs to Toyota.  Just two weeks ago the that compressor died.  This will be the 3rd Air Conditioner and the car has just 50K miles.  Shocking.  We're working with Toyota to see if they will do anything.

Chip wrote at 2011-03-29 21:07:55
Just got the phone call from the dealership saying that my A/C Compressor had failed and that it would cost ~$3000 to fix.  This is ridiculous.  I just replaced the central air in my house in San Antonio for $4000, and that was hard enough swallow. Its not like I live in my van.  Just wanted everyone to know that one more has been added to the list.  There has to be something that Toyota can do to fix this issue.  

Greg wrote at 2011-05-22 15:46:32
My AC just started acting funky.  Squealing when the car starts up and now it intermittently blows hot humid air that stinks every so often.  I will be going to my dealer to get it checked out next week.

We own a 2008 XLE AWD Seinna. The AC just started blowing hot air. After reading all the posts, does anyone have any additional answers. The van is at the shop now being looked at. The dealer said it is common and that they will be running a dye through the system, looking for leaks, and such. I am not too confident that they will fix it given all the people who have experienced this problem. Is there anyone out there who has had this problem in model year 2008 or greater?

I have a 2008 Sienna 100,000km,no a/c and just getting it checked this week, awaiting that info. After reading these posts was also wondering about newer than 04/05 models, thinking that maybe they fixed the problem since then.  Perhaps not.Any other 08s?

We have a 2005 Sienna van that just had the AC go south.  Were told cost to fix would be about $2000.  We have 103,500 miles.  We also purchased a toyota because we felt it would run for ever as they say.  

We live in the south so may have to fix, but going to get other estimates.

For the 2008- Sienna. We had ours recharged after 1.5 years as it was " low" 1.5 yrs into the lease. Now were 1.5 yrs later and hot air started blowing again- so 2xs in a year and a ahalf. They say they ran dianostics in 09 with no issues, now 1.5 yrs later and 2 months out of the lease they say it the rear suction tube for a $580.00 deal and will fix the whole thing -as there may be more issues for $970.00. What a sweeheart deal-not. Still working on this. Obviously they have an issue.

George wrote at 2011-07-31 01:03:54
Toyotas are a piece of junk. Their corporation belittles its customers and always point to users as the problem. This is why American car companies in past decades lost their market share to the Japanese. Looks like Toyota is about to lose their market share as well.

1-Report this to your local BBB.

2-File a complaint with the DOT.

3-Keep all documents and price quotes.

4-Look into local lemon laws.

5-Don't buy Toyotas and recommend to your friends that they don't buy them either based on your experience.

6-Local news has consumer reporters. You should be contact them about these scams.

7-Don't subscribe to Consumer Reports this car is one of their top picks. They don't do their homework.

I would love to hear from someone - anyone - who has had some luck getting Toyota to help pay for this repair.  Our 2004 Sienna has over 120K. The a/c started to go out in the fall of 2010.  It would work for about 10 minutes and then stop.   We saw all these posts last year and didn't have money to fix it then.  We had to give in this summer with every day being over 90 in Cincinnati.  Had a very good shop (a/c experts) look at it for about 9 hours and couldn't fully diagnose the problem.   I'm dropping it off at the dealership tonight and am very worried about the cost to repair.  I can't afford a new car, but also can't afford a $3000 repair.  But I NEED this car.  Busy kids, busy family....

Jonathan wrote at 2011-08-04 18:47:37
I'm swearing about Toyota Sienna A/Cs too. My old '98 Sienna developed leaking A/C lines when it was about 6 years old. I would get them fixed only to have leaks develop every other year. At one point, my local (non-dealer) garage said that, due to corrosion, trying to replace a line would likely break other parts at greater cost. Toyota appears to use poor quality materials on their A/C lines but also their brake and gas lines which seem to rust / corrode faster than any other component.

This week, my 2006 Sienna with 115,000km on it has developed a leak in one of the A/C lines and all other lines are badly corroded. Unfortunately parts are on back order and may not be available for a couple of weeks. Replacing just one line will cost $850.

I have a 2009 Sienna and its been in for AC 4 times now...once in 2009 when they recharged the system and again 3 times this summer (2011)recharged the 1st time, said they fixed a leak the second time and they still have it this 3rd time and not sure what is going on.

My advice - get a second opinion!  My 2004 Sienna air conditioning was working intermittently and slowly getting worse.  Toyota dealership said it needed a new compressor, clutch, the whole works - $5000!!!   I took it to an independent shop - they determined it was a faulty relay - $50 part!  A/C has now worked for over a month with no issue, so I am certain the second shop fixed it. This is clearly a cash cow for the dealerships, so check twice before you pay thousands of dollars.

2008 Toyota Sienna, 32,000 miles, one month out of warranty, was told the rear a/c lines are corroded and was going to cost $1000, this also happened with a Villager we owned, 3 times over 10 years. Mercury said they use steel clamps on alum. a/c line, add salt you got a $1000 bill. So we asked the Toyota dealer about this, he said Toyota has remedied this problem, obviously a lie!At $300/year for a/c, I'll roll down the windows as I drive to the Honda dealer!!

2004 Sienna clutch/compressor out for the second time.  First repair Aug 2007, 3.3 years after purchase.  This will be the third new A/C in a car that is less than 8 years old.  TSB AC003-05, not life-threatening, what does the consumer have to do?  Send Toyota the average temps in Central Texas for the summer?  Experience heat exhaustion?  Toyota owners buy toyotas for reliability, preventative maintenance, how about Toyota prevents heat stress and exhaustion (and improves consumer confidence) by recalling this inferior AC clutch/compressor/relay system?

M '04 XLE AC went out today at 160K.  I guess I'm lucky compared to most.  Dealer quoted $3300 for repairs.  We are going to farm it around for second opinions, but suffering through AZ spring at 95 degrees will test my resolve.  I'm not sure in this economy that I want to buy another over-priced used car.  

WHY was this not a recall?  Total dissapointment Toyota.  Shame on you.

I had warm air blowing in my 2008 LE Sienna.  Took it to an independent and they quoted $1100 for rear AC lines.  This worked for the drive home from the shop, then blew warm again.  Back to shop: oops, rear condenser damaged too--$1300.  At <4 yrs old, and <50K miles, it is way too early to have a $3000 problem.

2009 Sienna XLE with rear air, 68Kmi.  Same problems as described previously with corroded rear coolant lines.  Dealer showed me where lines are located under a cover in rear passenger wheel well.  Poor design causes dirt, salt, etc. to build up on the lines and cause corrosion.  Quoted cost to repair >$2,000.  Talked to Toyota and Certified Used Car reps. Told me "Too Bad, Not Our Problem."  They refuse to acknowledge it as design problem.  Lost this customer for sure.

Well, I didn't realize this was such a common problem with Siennas until I read all of these posts - I thought it was just our Sienna.  We have a 2005 and last year at 140k miles we had to replace the engine.  They said that if the oil isn't changed every 3000 miles on the dot the engine will become over gunked and die.  It would have helped if they had let me know this when we got the van.  We got regular oil changes but everyone has always said 5000 miles was fine.  Then A/C blew hot and cold for a while and now is just blowing hot air.  I got an estimate today from a non-dealer and the cost to replace the compressor is $1105 which we were planning to pay but now I am nervous thinking it will continue to have problems.  This is really disappointing news - I have 3 small kids and there is no way we can go without air in the Florida heat.

Add another 2005 sienna owner with blown a/c compressor at 89k miles.  This is my 4th and last Toyota, as this is 3rd major repair, $1500+ in the last 4 months.  Trading it in for a Subaru.  Shame since all the other Toyotas ran well close to 200k before I traded them in for a new one.  Cannot afford more repairs when total is same as a years worth of car payments.

My 2005 sienna had a same problem this week at 158K miles.I first heard some kind of unusual noise then the a/c started to blow hot air. I search the google today and find there was a toyota technical service bulletin ac003-05, dated july 12,2005 title a/c compressor durability improvement. Toyota actually knew this problem and they know sooner or later 2004,2005 sienna owner would have a/c problems. I got an estimate from crown toyota in ontario, CA and the price to replace front and rear evaporators,compressor/clutch and condesor,flush line and recharge is $6953.66. By the way i do the maintainance timely.

The original AC system on a 2000 Sienna LE went into the toilet after 64000 kilometres, and the second (new) system went into the same toilet without warning after just 7200 kilometres, yes, about 5,000 miles. The independent garage operator apologized for the "crap" he was obliged to install vthe first time, and ate 2/3 of the total cost (parts and labour) for the second new,replacement system. It is my understanding that Toyota does not manufacture any of the AC components,but apparently buys whatever it needs at the lowest cost it can get, and may be skimping on quality control. The replacement failure occurred (compressor clutch froze) while we were in a rural area of Northern Ontario, vehicle conked out at the edge of Sturgeon Falls, but we were able to get a tow.In another 30  minutes we would have been stranded many miles and even more kilometres from a garage where we ran a belt around the generator and alternator to keep us on the road for the remainder of a 2500 kilometre (1500 mile)trip.You may imagine the carping when I got back to Ottawa, but I felt better when the dealer also dumped on the AC manufacturer, and took him off the AC sourcing list. However, my beef is with Toyota, and since we have lost confidence in that company's product we are looking at an alternative.

Add me to the database: 2005 Sienna with 75,000 mi.  Compressor failed.  Took it to a Toyota dealer, which diagnosed that the failed compressor shed metal shavings that contaminated the A/C system.  Condensor is shot, as well as some "dec" bag needs to be replaced.  Dealer cost to fix: $3,600. Dealer recommended I call corporate Toyota to report issue, open a case file, & try to get compensation...They politely listened & opened a case file, but offered zero help.

My wife's 2004 sienna vans a/c went out. 2 mechanics told me the evaperator core was leaking and 1 declined to do the work. It will take 20 hours of labor to dismantle the dashboard and replace the core and expansion valve. Thank G-d I was able to get the OEM parts brand new on eBay for $80 delivered vs over $1,500 at the dealership. No that wasn't a misprint. The labor will cost me a whopping $1,900 next week. Totally did not expect this from Toyota. Why engineer a car that is so difficult to repair when something does go wrong??

2009 sienna with 72,000 kms.  CE or LE. Just told Lines corroded and compressor shot as they figure a stone came through grille and cracked it.

Estimate of close to $1800 to repair. I call BS. First noticed problem last fall at about 65,000 km. and dealer said the cant test it until it warms up.

2004 Sienna, AC started blowing intermittent warm air, having done some wrenching in my youth I thought I would look into the problem myself. I do not have a set of AC gauges, so I purchased a can of Arctic Blast with a pressure gauge attached.  I connected the can and the pressure gauge pegged on max, I noticed the compressor wasn't clicking on, so I cycled the AC on/off button, the clutch engaged and the pressure dropped some to the highest "usable" setting. Having not read this forum yet (and not knowing about the issues) I thought that maybe the high pressure was causing an open circuit in the compressor clutch voltage. I stood back and gave the high pressure AC port a quick depress to see if the high pressure would subside. The late afternoon sun was behind the freon plume and me, I could see shinny particles emanating from the blast of gas. This made no sense to me until I researched AC issues on Sienna's.  So if you are having problems and want to confirm metallic particles in your system, have some comfortable with mechanics perform this little burp test.

I have a 2004 sienna and the air condition did not put out any cold air but the fan worked fine. Took it to the dealer and just  had the freon changed for $350 and it failed on the way home. Add me to this list. I could make the air condition work some of the time if I turned of the A/C button pressed the Off button and them pressed the Auto button. This worked some of the time but not ever time even after I had the freon changed.

2005 Sienna van, 212,000 miles, ac compressor working intermittently if at all.

2006 Sienna (bought new), AC did not work well out of the dealer.  Took the car back for repair.  Dealer said they fixed it but they didn't.  AC went out so was the warranty.  I took the car to another auto shop.  They found the rear AC was broken.  A few years later, AC is not working again.  This time, the auto shop couldn't find the leak even after adding dye.  They suspect the evaporator which is labor intensive and expensive to fix.  This is so frustrating.  I'm going to buy a SUV soon but Toyota is not part of the consideration.

Add me to the list of victims.  2005 Sienna with 105k miles.  Compressor went out, sending particles through the A/C system (according to the technician at the dealership).  As others have said, I bought a Toyota expecting good reliability, but this will be my last.  There should be a recall.

2006 Toyota Sienna XLE Limited original owner,  We have replaced our AC Compressor 3 times, that's the 4th compressor for our van including the original.  We are the original owners and have averaged 9600 miles per year, have had the tires and brakes replaced on average every 25,000 miles at a cost of $700each. The only time a compressor was covered under warranty was in 2010 (1st replacement). The AC compressor has subsequently been replaced in July 2013(2nd replacement)and today July 2016 (3rd replacement). It seems after looking at this blog that there should be a recalled on this item as a systemic problem.
