Hello all, first post. Been doing some searching, but I can't find the answer I need. I recently purchased a 2000 Denali, with 157k miles. I have a few problems in the interior, and I think they are all somehow related... but maybe not.
Issues that I am having:
1. No dome lights whatsoever. Not when you push their individual buttons, not when the doors are open, not with the dial on the dash turned all the way up, not with the override pushed in or out.
2. Door locks are intermittent. Sometimes the lock fine with both the door switches and the keyless fob. Sometimes only a few work, sometimes none.
3. In line with #2, sometimes the horn beeps twice when I lock them with the fob, sometimes only once.
4. The power mirrors do not move at all with the switch.
5. The chime for when you leave your keys in the ignition after turning off the vehicle only works sometimes.
6. The chime for when you leave your headlights on after turning off the vehicle only works sometimes.
Things that may be related but work fine:
1. Bose radio works flawlessly. Sometimes it loses the correct time on the clock but thats it.
2. Power windows work great.
3. Gauges light up perfectly and all gauges read properly.
Things that I have checked:
1. All seemingly related mini-fuses in the dash panel on the drivers side.
2. All of the big fuses in the fuse block in the engine bay.
Any more ideas? I've read something about a Body Control Module (BCM) but not sure what it does or where it is located.
thanks in advance.
