i have a question about the so called security system in the 87-91 bonnevilles, according to the owners manual, the car has a factory security system with a warning light that flashes when the doors are unlocked and stays solid when they are locked, meaning the system is armed, and if a door or something with a sensor is opened, the horn will sound, etc etc etc.... well mine dont do that... the light works and all but nothing else, not even a burp from the car, is there some kind of module that controls this or is it just a dummy system, with one of those idoit lights :?:

You are seeing the proper operation at the light? Flash vs no flash? I am sure it'* a real system and some part of your is merely not working properly.

the experts w/manuals will chime in soon.

Try opening one of the front doors (passenger works best for me) and press the power lock button. Wait for the Security light to go solid, but keep the door open. The alarm should go off...at least it does for me. For some reason my driver side door doesnt make the security light go solid when I press the lock, but any other door will. Don't know why...

yup, light workie, just nuttin else, maybe it has something to do with me not being able to get a damn keyless remote to work on it, it goes into the programming mode, and recognizes the remote with the unlock/lock, but after it gets out of that it magically forgets it again, my car may be black, but i swear its a blond at heart :?

i remember ive done that in the past and it didnt do anything, and my drivers door makes it go solid

Silly question.... but does your horn work?

I know in my 91 SSE the horn shares the same fuse w/ the fog lights. :?

yup horn and foglights work

open all the windows in the car.

open the drivers door. (security light should start flashing)

Press Lock (Security light should glow solid)

Close door (security light should stay on for a few second then go out, and you should hear a slight sound of the locks double checking themselves) if the light doesnt go out there is still something open. it could be the latch sensor on the trunk or the hood being faulty. i have seen several of the trunk latchs fail.

wait a few seconds

reach in teh door and manually unlock the door and open it (if that doesnt set it off, try it on all the doors

the light stays solid all the time, never goes off unless the car is running

there is something wrong with the system.... i can get back to you tmorrow... i have the schematics for the system on cd around here somewhere...
