Rear passenger window wasn’t working… any tips on diagnosing, I’ve been following the wiring diagram and getting inconsistent voltage sometimes 12 sometimes 1. I tried to use my Milwaukee 18v battery to start the motor but it was a no go, thinking that the motor is bad but it is a newer one that the previous owner put in, and he said it didn’t work when he put it in. Rear driver window doesn’t work from the rear switch but does from the front most of the time.. is it a big grounding issue?
