About a month ago, my passenger side power window started getting really stubborn. I would have to press the switch quickly a few times in order for it to respond. But now the window has stopped working completely.
Here's what I did to troubleshoot:
First I removed the front door panel, then removed the front power window motor. I tested the connector with a multi-meter and when I hit the switch, the meter read +12.2v or -12.2v. This told me the motor was in fact getting voltage and I could rule out the switch or the circuit being bad. The next step was to test the motor itself to see why it wasn't spinning even though it was getting voltage.
To test the motor, I removed the rear passenger door panel and the rear power window motor and swapped it for the motor from the front window. It worked! - But why did the front power window motor work fine when I hooked it up in the rear door but it didn't work in the front door, and at both places the multimeter read the necessary 12v?
Please help me. Any ideas would be greatly appreciated.
