Question about 1999 GMC Suburban
Power door locks work fine from remote control (keyless FOB). They do not work from power buttons on either drivers or passengers door. This includes lock and unlock. Rear cargo switch does nothing either. Lock motors/actuators obviously work. No blown fuses. Not sure how/if can troubleshoot door switches. All other accessories work - mirrors, windows, seats, lighter sockets (all of em), wipers, washers, radio, etc.
The last post by maddog1321 was exactly what I had with my right rear door. The electric locks would not lock and unlock, and you almost couldn't do it manually without my feeling I was about to break something. I took the door panel off, oiled everything and got no relief. Finally, I saw the above post and drilled out the aft-most pop-rivet. THE WINDOW WORKED PERFECTLY! I didn't drill out the forward (closest to the handle) pop-rivet because I wanted to do one at a time so the solenoid would not fall out of place. I then put a new pop-rivet in place of the one I drilled out. I then reinstalled everything and the locks work like new.

I have has my door panel off and realized that if the window switch becomes loose or falls off this will prevent the door switches from working. As far as the back window and lock. Same problem same problem on mine. The rivet that holds the actuator for the lock corrodes and the actuator binds in the window mechanism. Not easy to fix but fixable.
