Instead of making a ton of new threads, I'll just keep them in here.

2002 Burb Z71 5.3L

1. Only one of my 3 a/c adapters in the front work. How do I try to fix them?

2. Center console. Both a/c adapter and stereo controls don't work. I've been trying to find them locally in junkyards but all trucks in that year are totally stripped out. How can I trace the wire back to fix the cig lighter? I know there's no hope for the stereo unit except for a new one, anyone got a used one they don't need for sale?

3. My ABS/Parking brake light keeps coming on either while driving or just start up. I've looked on this site and it might be a simple corroded wire.

If you guys have any help on tricks LMK.
