Again there is a switch at the back of the hatch that controls the inside locks, that doesn't work! The lock switch/ control at drivers door doesn't work and nor does the switch to open the back hatch! I have power to switches at drivers door, the fuse in the inside compartment fuse panel is good, I have changed out the locks relay but NO success! I don't see anything in engine compartment fuse box that protects any lock circuits!! What about vehicle computers? Terry Johnson
Power Door Locks Circuit Description
The power door lock system incorporates door lock switches on both front doors and on the RH D-pillar, door lock motors in all passenger doors and in the RR cargo door, a door lock relay and a door lock control module.
Power for the door lock switches and the door lock control module is supplied from the CIG LTR fuse 13 through CKT 640 (ORN). Power for the door lock relay is supplied from the PWR ACCY circuit breaker through CKT 540 (ORN). Ground for the door lock relay is supplied from G202 through CKT 150 (BLK) and ground for the door lock control module is supplied from G400 through CKT 150 (BLK).
The door lock motors are reversible and both sides are connected to the normally closed contacts of the door lock relay. Those contacts of the relay are connected to G202. When any of the door lock switches are placed in the lock position, voltage is supplied through CKT 195 (LT BLU) to the relay lock coil. Since the other side of the lock coil is connected to ground, the coil is energized and it pulls the lock contacts closed. Voltage is then supplied through CKT 295 (GRY) to all the door lock motors and the doors lock. The unlock function operates in much the same manner except that when any of the switches are placed in the unlock position, voltage is supplied through CKT 194 (WHT) to the unlock coil of the relay and CKT 294 (TAN) supplies voltage to the apposite side of the door lock motor and the doors unlock.
Door Lock Control Module Description
The door lock control module is used on vehicles equipped with cargo doors. The purpose of the module is to lock the cargo doors after a lock cycle has been commanded from any of the door lock switches with the cargo doors open. When the RH cargo door is open, the module receives a ground signal from the closed contacts of the rear door jamb switch on CKT 1897 (ORN/BLK) to G400. When a lock command is received, the module retains this input until it receives an open input from the rear door jamb switch. Then the module sends a lock command through CKT 194 (WHT) to the door lock relay and the doors lock.
Rear Cargo Doors Description
The power door lock motor will not operate unless the rear cargo doors are fully closed. The power door lock motor is in the right cargo door. The contactors are on the rear cargo door opening on the body and on the right cargo door.
SOURCE: Hi, I have a 2003
I have a similar problem. The remote sometimes opens all doors, and other times it will only open the 2 rear doors. Once inside the vehicle, the driver side window controls intermittently operates all windows and doors. It has no effect on the 2 rear doors, as the window controls still work. This behavior happens intermittently while driving the vehicle.

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.
SOURCE: On my 2003 gmc passenger power door nothing works. can
it sounds as if the wiring harness to the door may have come disconnected or broken you have to open the door panel and check the connections manually
SOURCE: I can't lock the rear hatch door on my yukon
The lock is stuck in the "locked" position.
When you close the hatch, it is jamming the latch hook into the wrong area.
Manually open the hatch. Unlock the hatch (even tho the hatch is already open). there are two bolts holding the metal "loop", the loop has moved. Adjust the metal loop and close the hatch / lock it, etc.

this problem i have repaired many times.. it is normally a broken wire in the flexible rubber tube between the door and the doorjamb from years of flexing back and forth when you open and close the door.. i hope that helps
