Hello All, I'm attempting to repair my mirror switch, but since many of the smallest parts are missing, I can't seem to reverse engineer how the switch itself works. I have the workshop manual with the circuit wiring diagram, but that neither explains how the switch itself works, nor the workings/schematic of the motors themselves. There are four wires going into the motors, but no explanation which wire is for which motor (up/down or left/right) or polarity. Any assistance or even simple explanation of how a working switch operates would be greatly appreciated. Thanks, -Hank #1619
