Help with Power Door locks

[Bamapilot]

I have searched the forums pretty well and have not found anyone else with the exact same problem, so here goes.

2002 Z-71 Tahoe

My driver's side power door lock does not work at all. It will not lock/unlock any of the doors. No movement at all. The passenger side will lock/unlock all of the doors except the driver's side. When I put it in drive all doors except the drivers will lock and when put it in park all doors will unlock except driver's door. No movement at all. Also, the power mirrors do not work. All windows work fine from all doors.

I have checked all the fuses I know to check in the door jam and under the hood. Didn't appear to be any related fuses under the dash.

Thanks!!

Please Help

No one else has had this problem??

Have you taken your door apart and checked the connections at the switches? Also may be a short in one of the wires as well or just a bad switch.

Since nothing appears to work on the lock maybe you should check for broken wires in the harness leading into the door.

I have checked the connections to the door lock switch. All seems fine there. I am going now to take the door panel off to check other potential wiring problems. I am not getting 12v to the switch, so as you both suggested, possibly a broken wire. Is it possible that there is a bad relay? Would that keep the power going to the switch?

Thanks!!

I have an 08 Tahoe, and have had this problem for a while, I had it in the shop to fix a year ago but it happened again, I also have no cruise control and the driver passenger window goes down with the control button but not up, however i can put it up with the button on the drivers door
