Hi all. Having an issue with the RR power window. It will not go up with the door switch but will go down. And will not work at all through the master switch on the drivers door. I have been able to jump the wires at the switch connection using a 12v battery and was able to get the door up under its own power. We tried replacing the master switch, changing out the motet etc. but can’t figure it out. Any advice on what to check? Thank you!
