Question about 1999 GMC Sierra
The inside door locks no longer work on the passenger or driver side. The windows still go up and down. The lights for the locks no longer come on at night either. However the keyless entry still works to lock and unlock the doors. I checked and have power going into the switches on both the passenger and driver side. I'm hoping it's a fuse somewhere.
The leakage inside the door lock maybe damage or deslocate try to check

I had the same problem in my wife's 2003 Yukon Denali. The power seats and passengers side window wouldn't work. Turned out to be a blown Buss Type fuse in the Underhood Fuse Block. It is the one marked MBEC 1 50amp. Hard to tell if the are blown so look very carefully. Should look like a hoop with two shiny solderlooking bubbles on either side. On my blown fuse, it caught my attention because it looked like the solder was missing and I had to look very closely to see the bottom of the "hoop" was open. They are very hard to remove and must be pulled straight up.
This type of fuse looks like a red square with a clear plastic top showing the fuse link under the plastic. On my vehicle it is on the top row second one from the left.

SOURCE: Power Door Lock Problem
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.

Take The Driverside Control panel Off The Door,And Check Conection On The Main Switches,These Vehicles Have Locks On Them, And If They get loose The Stop Working,Also Check The Little Switch Towards The Front of Panel,It Also May Be Loose,Use Caution,The Clips Are Fragile..

Inspect or replace the window lock and unlock switch on the drivers door power window switch. There is a lock and unlock switch that will disable the switches to the other power window in the Jimmy. Check to make sure that switch is in the unlock position to have the other power window switch to work.
Thank you for suing fixya and good luck.
