The previous owner removed the rear wiper motor. I got a new motor, but I'm not getting any power to the wiper motor plug in the lift gate. There's power at the switch and I traced that back to a connection on rear driver's side, behind the interior side panel. There's power at that plug, but no continuity from the mating plug that goes to the wiper motor. My question is...is there another plug around where the wiring goes into the top of the lift gate? If so, is there any way to check that it's connected without removing the lift gate?
