I just bought a 2001 Tahoe. I removed the driver's side door latch and cleaned up the contacts to fix the dome light / radio turn off issue. While checking a couple of other things... I noticed that the lock/unlock button doesn't work on the driver's door. The remote FOB works fine. The owner mentioned that he bought a new window control module for the driver's side. I checked and all of the connections seem fine. Any thoughts?

While I'm at it... the door insert that the 7mm screw at the handle screws into is missing. Any thoughts on where to get one of these?

One more that's not on that list: Lock/Rearview Mirror fuse (3A).

I noticed my mirrors didn't work this morning. Found the 3A fuse was blown and that the same fuse controlled the mirrors and the lock/unlock button. This fixed the problem.
