So my passenger side rear quarter window is having issues.
it will go down but does not respond to the switches on the Driver side or at the switch for the window itself. I pulled the motor and tested it and it works fine, I reinstalled it and ran a battery direct to the motor and it worked fine, window went up. I Took a test light, and at the switch by the back window, it gives energy in the down position, but not in the up position.
I am assuming that by the wiring diagrams that if it was the power window relay at risk, either it would work, or not work at all ? Relay looks super simple 12v in 12 volt out, and a 12 switched power. Also Other windows go up and down OK.
but what would cause both switches to function the same (wtih no ups, just downs ?) on the same window ?
