Hi, I am desperate need of help.
I lower the window (driver side) park the car and the window will not close, dead as a door nail nothing clicking no sound or movement so I left it like that to deal with it the in the morning but to my surprise the battery was totally dead not a drop of juice no problem with the battery before fairly new battery. I charge the battery but the window still dead I switch buttons and still dead I take the door panel off and that is where I need help testing the wiring. The two prongs connector reads 12v on both prongs? The 4 prongs on the bottom I don’t know how to test them because the color code is different on both ends (switch and motor). I tested the motor removed and it runs forward and reverse.
