Good Day,

I am fighting with some electrical issues on a 97 Tahoe. The interior lights stay on. The "Dome Light Override" does not stop it, eliminating door switches as the cause (as deduced from the schematic). I believe the lights get a ground from this module, but it is buried up in the dash. I hear the relay click when I operate the door switch, so I think it is a stuck contact or a wire shorted to ground. It there an easy way to get this out or do I just start disassembling:superhack:?

You have a shorted wire somewhere in the harness for the lights...... I wouldnt think the BCM would be your issue..... Pull the positive lead off the battery, pull a bulb, one side will show short to ground if a wire is shorted..... If module is flakey will only ground with battery hooked up.......

Called it!

Good call Lester. I had already dug in when I saw your reply. I had unplugged the BCM and the headlight switch assembly and still had the lights on. By pure luck, I started on the driver's side pulling up the door jamb plastic to get to the harness. It looks like there was a loop in the original harness and when it was pulled tight it kinked and eventually broke the insulation. I got everything back together and it seems all good. Thanks for the reply.

No pics

Sorry, no pictures. I will be installing a brake controller today. Seems simple enough other than a tight fit getting to the brake switch wire.
