Electrical Trouble ( LSS )
I have a 1997 Olds LSS that is having iisues with the courtesy lights.
The problem is simple...they wont shut themselves off.
The interior lights are able to be controlled by either their individual switches, or as part of the illuminated entry system.
I replaced the the BCM yesterday, as a diagnostic tree from a GM tech manual seemed to indicate that it was the problem. However, it has seemed to make no difference.
The lights worked just fine for a trip that took several hours. Once I arrived at the destination, the car sat idle for several hours. When I restarted the car, the lights came on..and would not shut back off...even if i tried to turn them out by their own respective switches.
The only way to kill the lights was either by disconnecting the battery, removing their individual bulbs, or by disconnecting the BCM. I did the latter, and the lights soon went out. While the BCM is unplugged, the lights will not function , save for their own switches.
However, I did notice that if I disconnect the neg cable from the battery, and then using a test light, connect the clip to the cable and touch the neg terminal of the battery I get a dim pulsating light in test light.
ANy ideas ?
