    this problem only happens occasionally and the horn for security goes off too, this is all related to the relay or loose wire, I take it. Can I fix it myself-I have no job now and can't take it to a garage

    I've been told by someone that it's probably the BCM. He told me where the delay relay was 1 1/2" from SDM. This was an online answer I got. Don't know what the letters stand for. So I'm really confused now.I can't afford to just take it in to a shop, we're on a fixed income. My husband said maybe auto zone might help if we knew what we were looking for. Someone in the past has put ground wires who knows where. I forgot to say my pass. seat doesn't work right nor the antenna. Tell me in plain talk what that other guy is talking about and just as many ideas that could be solution to this.

Chek the accessory time delay relay for continuity, it is located at the wiring harness about 1 1/2" from underneath the drivers side seat. More then likely this happends when your body control module (BCM) goes bad. Click on the link below to view and then order a replacement:

Your post was not clear, but I am assuming you are talking about the radio not turning off

I've seen this a lot and it appears to be a programming concern on most vehicles that require new updates for your ECM

however, some times it is a defective accessory delay relay and other times it is a shorted control wire for the delay relay

either case, depending on your electrical diagnostic experience and availability of professional scan tools, you may want to seek assistance from the dealer or a VERY GOOD garage with lots of electrical experience

Why wont my radio shut off on my 97 eldorado

In Cadillacs ( I have an Eldorado ) the radio and power to things like your windows and power trunk release, will stay on for up to 15 minutes after the engine is shut off and the keys are removed. However once you open your car door it should it should break the connection and shut the power off to your radio and windows, If it is not cutting off the power i would look for a connector that should be attached to the pin that controls your interior lights in the door frame. Probably a good cleaning or replacement of that switch should fix your problem. If that does not cure your problem then take it in to an auto electric shop to have them trace the wires to find out where a cuircut has been stuck (fused) in the on position.

Remove alternator on 99 eldorado norhtstar

Okay, i will start by saying this is a job that should only be done by someone who works on cars, first thing first is if your car has onstar you must disable the back up onstar battery, if power is removed the back battery will be turned on and run until it drains out and then will need to be replaced , does not matter if you reconnect battery quickly. so first make sure key is off and out of ignition next open driver door , leave open , dissconnect battery, this way the back onstar battery is not turned on.

With that done you will next remove the belt then remove the front alternator bolt.then you will need to drain and remove the radiator,next you will need to raise and support car, remove front splash sheild, next loosen rear alternator bracket from engine.

Remove top bolt,front lower mounting bolt and lower rear mounting bolt, remove upper rear mounting bolt.
Remove air duct from rear of alternator. Disconnect wiring from alternator. next remove front alternator/ A/C bracket. rotate alternator and remove. To install reverse procedure .

Every time I open the door nad drive the car, then shut it off the alarm goes off and I can not find a way to shut it off. How do you do it? I also do not have the key fobs.

quickest way i know of here is providing its a factory immobilisor and not a boy racer add on then take the chip out of the key and tape it under the shroud next to the transponder ,This way the car thinks its got the key in and this will stop the alarm

2005 Cadi CTS Radio Pre-Sets

1988 CADI Eldorado Biarritz, 4.5 liter v8: locked keys in car, called locksmith he put inflatable air bags in door to stretch 4 space to slide his crooked metal stick in and reach pull the handles, push electric door lock button/switch and manually but doors would not open. He than pulled the keys out of ignition and out the crack. Guess what, both doors sounded like they unlocked with the key but would not open. Is there some kind of anti theft protection that kicks in when you mess the doors and locks inside? Help, I have my keys but car doors will not open. Did stretching or forcing doors open a bit with these airbags possible cause damage?

99 eldorado. trunk and gas door pop open

There is corrosion at the positive battery cable and the terminal is probably  about to fall out of the battery. Clean battery terminals, replace bolts and spacer if applicable and recommend battery replacement
