Hello my name is ***** ***** I can help.

The same power feeds the left rear window. Does it work?

Do you have a test light or volt meter?

I have seen the wires broken in the flex tube between the driver and body.

The driver door switch is a module and locks up some times. If you unplug it and plug it back in some times it starts to work.

If none of this helps we will have to do some voltage test.

Please get back with me.

Thank you

Strange thing happened I went out to open the car and it unlocked and the door is working and all the controls are working so now what
Expert:  GM Bob replied 11 months ago.

The door control module may have locked up than started to work.

There maybe some codes stored in the body control module

Sorry I just got home. The only thing not working now on the driver door is the heater switch for my seat. It goes on but then as soon as it starts warming up it shuts off. Otherwise everything is working now!

Can you post your VIN#

As for the heater it may set a code to help find the problem. They shut down when the heater pad has to much resistance in the wiring .
