2000 door lock left side switch & remote not working

[Dave Smith]

Any help would be wonderful. I guess I have a wiring problem. The passenger side door lock switch works fine. The Drivers side switch does not lock or unlock the doors. Also the remote does not lock or unlock the doors.

Does anyone have wiring diagrams to send?
Anything common for the left side switch and Remote?

Thanks

Ideas anyone?

I would start by checking the battery or replacing it in the remote. Then I would rip the driver door panel off and check power to the switches. Also check the switch for continuity when closed.

Actually, the most common is broken wires in the door boot. You'll find gray (lock) and tan (unlock) in the kick panel. Test to see if there is any juice going to these wires IN THE KICK PANEL. ALso, these are reverse polarity which means when one of the wires is + the other switches to -. So, you'll need to check that too.

I do not think the BCM could be the problem if it is actuating the other locks. But, you say it won't work ANY of the locks with the remote???The BCM is under the column. If you want to check there the power Lock is lt. blue + pin A4, brown plug at BCM and Power Unlock white + pin A3, brown plug at BCM
