92 camry left rear window problem

My left rear window motor has not worked for several years. Suddenly several weeks ago the window just dropped. I knew the regulator had failed so I replaced the regulator and the window still was not working up or down. I ran 12 volts to the new motor and it works . I removed the master switch and disassembled and cleaned up still nothing. Ordered new master switch still nothing. All other windows work. Checked power coming out of the switch and it is there. Tried testing current at the motor plug and only get power on one leg. The confusing thing is that the wires that have power with the switch on up and down are not the same color at the rear door making me think the wires go elsewhere before going to the back door. Anyone have suggestions thanks

Check the wires for continuity at the point where they go from the body to the door. Opening and closing the door repeatedly many times causes them to break.

Thanks for the help!
