The rear driver side window has stopped working. When the switch is pressed. There is a click that is coming from the Left Rear Door Module. Is this module my problem? Or is there an underlying problem?
I unplugged the rear switch hoping the switch was bad. Now that I think about it though. I believe a good switch has to be plugged in for either switch to work. Am I correct on this?

I would check power to the window regulator. Pull the door panel off and connect the switch and check the power to the regulator.

I do believe that you have to have a good switch in the circuit to complete the circuit and data loop.

I am going to check the window regulator this coming weekend. Had to much to do this past weekend. I did put the passenger side switch on the driver side. Still didn't work. So I am at the regulator/motor. Do you know which wires I need to check for current?
