Hey all. I am having a very weird problem with my 1996 Bonneville SE. A few
days ago, my Power Locks, Power Antenna and Interior Lights stopped working,
all at once. I could sit in the car and hit the power lock button and it
to lock the doors, but it was as if it was not getting
enough power, and the BCM would buzz. Also, the Fog Lights were working as
the Interior Lights. IE: When you opened a door, the Fog Lights would come
on at around 10% brightness and when you hit the Lock button on the remote
with all doors shut, the main headlights blink (it always does this as
fog light blinks (usually both blink, same as the
headlights) and the horn chirps. However, the locks only *try*
to work. With
any door open, you don't get anything from the locks at all. Not with the
remote, not with the button and not by putting the car into Drive (which
usually locks the doors) or shutting the car off (which usually unlocks the
doors). As I said though, if the doors are closed, 9 times out of 10 they
try to lock or unlock. So, I tried another BCM. No change. I then was told
by someone to try checking out the BCM's ground wire on the passenger side
under the dash. I moved it around a bit and it all functions started to work
properly again. The only difference was that the keyless entry remote had a
much more limited range, but that could be batteries or something else.
Anyhow, I decided to clean the ground wire up really well, so I took it off
cleaned it up and hooked it back up. When it touched the metal of the car it
sparked (normal?), but I hooked it up anyhow. Now, the same problem is back.
Exactly the same as before. I tried another BCM again and the only
difference this time is the BCM will occasionally beep when I press the Lock
button too many times in a row and the 'Fasten Seatbelts' light will try to
come on the dash board when this happens (even though the seatbelt is on).
Also, if I turn the car on with the seat belt off, the 'Fasten Seatbelts'
light comes on, but it goes off if I turn the headlights on with the
Very confusing I know, but *any*
help will be very appreciated.
I am sorry for taking up so many people's time but I could really use some
help with this. I have asked several different dealers and none of them can
think of a problem. I can not afford the $95 an hour that the local dealer
charges, so any help is greatly appreciated.
