I recently picked up a set of EX doors to swap out the internals into my manual doors. Drivers side was perfect, no problems... passenger side is the issue... I can't control it from drivers side, and from pass control it only goes down... When I put a wire tester into the "up" wire between the switch and motor on pass side, it shows a signal when I hit up on the switch, but I get nothing from the motor. Does that mean switch is bad, motor is bad, or wiring from switch to motor is still bad? Down works perfect. Any ideas?
