I am drawing power from the plug where you install the window's electric motor, and I know for a fact the the electric switch is working (I hooked up the switch to the passenger's side and it worked like a charm) also, the electric motor is working because I hooked it up to the car battery and grounded it and it started turning. All I can figure is that the aftermarket car alarm installed by the previous owner may be hindering it somehow. Just wondering if anyone has run into something like this and if so, what did you do?
