Question
QUESTION: Need to replace the front turn signal bulb on a 91 Cadillac DeVille and the 'Chiltons' manual I got says to first 'DISCONNECT THE LAMP MONITOR FIBER OPTIC CABLE". How do I do this (of course they don't show any pictures or diagrams for any of the steps they list for our car make %26 model)?
Is there a web site that has diagrams/pictures of the different systems in a 91 Cadillac DeVille because this manual I bought doesn't even show the correct configuration of everything under the hood? The pictures they show have everything flip/floped. I am not a total car repair dummy i.e. I changed the alternator in my son's Tempo at X-mas with no problems but I need pictures or diagrams for the first time. From what I have gathered, you have to pull the entire light assembly out the front of the bumper to change a turn signal light bulb OH VEY.
I just don't want to screw anything up...lol
Thank you so much,
Barbara
ANSWER: Hello Barbara,
Chilton manuals are too general (one size fits all-sort of).
If you want the diagrams and detailed instructions for everything you need to know on your 91 Caddy (if they go back that far).
Go to http://www.alldata.com. See if they have the information on the 91. If not, body and electrical is fundamentally the same for 92 and 93. I get nothing for recommending the site, however, the information is awesome and I use it frequently.
If you scroll down the list of applications and you see your car, pay the $25-$30 for a one year subscription. You will download more factory information than you will believe. You have a year to use this info. Additional cars are $14.95 each.
Everything you get is right out of the factory manuals.
Good luck!

QUESTION: Dear Rob,
To remove the lamp assembly to replace the bulb, do I have to "disconnect the lamp monitor fiber optic cable"? Will it mess anything up if I don't disconnect that cable %26 just undo the nut and pull the whole assembly out from the front of the bumper? I ask cause I don't know how to disconnect that cable nor do I even know what it is....lol
Thanks again.
Barbara
Hello,
Do not remove, twist or bend fiber optic because you will screw up the monitoring system.
Here is a suggestion--I don' t how difficult it is to replace the bulb because it has been years since I worked on a 91 Caddy, but if easy, I have a suggestion. Go to a parts store chain like auto zone, buy the bulb and most cases they are willing to install for a woman at no charge. My ex always had these minor things done for free.

| Comment | Dear Rob, Thanks for the info....(I chuckled about your suggestion of asking the auto parts guys to help me put it in....I use to get away with that kind of thing but now at 55 I don't even try...Although I have been known to take my daugher, she's 20 yrs old and pretty & just a doll, to auto parts or the mechanics for just the same reason. Light bulbs are usually easy to replace in most of the cars/vans I've had but I think Cadillac like complicate things. I am going to assume that when you say the fiber optic is for the monitoring you are refering to the "Twightlight monitoring' where the lights come on by themselves etc. We had to have that feature disabled 2 weeks after we got the car, the headlights wouldn't turn off AT ALL until I disconnected the battery. So the mechanic disconnected the system some how. (My son bought the car in October 2009 and it only had 46,000 miles and he's had to have a few rhings repaired but overall its worked out to be a great deal. Thanks again for all your help, Barbara | ||

Expertise
Alarm system questions cannot be answered on this forum. These systems are not what I can answer. Without being physically at the vehicle and not knowing what kind of electrical service has been done on the vehicle, there is no possible way to give an accurate answer over the internet. My expertise is in Ignition/key based anti-theft systems. These issues include GM VATS (resistor chip in key blade) PASSLOCK (MRD)-ignition lock rotation based, no special ignition key and the PKIII Transponder (computer chip in key) systems. These systems are not alarm based and are integral with the starting of the engine. This is why I cannot diagnose alarm problems without physically looking at the vehicle: Alarm systems are a completely different annimal than ignition key/lock based anti-theft system. Many alarm questions come from vehicles 10 years old, and since older, many hands that had been involved over the years.I am an expert in all GM factory (ignition/key based)systems. Alarm system questions pose to many situations beyond my knowledge as to what has been done to the vehicle over the years. Some guy may have actually wired the stereo into the alarm system. Who knows? Over my past 30 years in vehicle wiring repair, I have seen unbelievable wiring disaters done by guys that consider themselves "mechanics." I have seen stereos and alarms intalled using surgical tape. I have seen modules burn up, un-fused circuits, wiring jambed between the doors and even lamp cord used for a starter kill. To answer alarm questions over the internet without examining the vehicle is like asking; What does it take to remove a dent?
