Power Window repair pics
I looked for a write-up on how to repair a broken power window but didn't see any that had pics. So I took some quick shots when I diagnosed and fixed my drivers side window. First I noticed that the only window that didn't work was the drivers side,so that ruled out anything that all the windows had in common(like a relay or a fuse). Next I pulled the door panel off of the door(I think there is a write up on how to take the panel off in the archives).
Once I had the panel off it looked like this:(pic 1)
I pressed the window switch and I could here a click coming from the black box that I'm pointing at in the pic:(pic 2)
I figured it'* some kind of relay or solenoid. Next I found the motor, disconnected the plug going from the black box to the motor and tested the plug with a simple 12 volt probe to see if there was any power going to the motor. And when I flipped the switch to lower/raise the window the light on the probe turned on meaning I had power to the motor.(pic 3)
I loosened the three bolts holding the motor in place and used a small flat head screwdriver to pry the motor from the main gear(you'll see the gear after you remove the motor from the door frame).
Once I had the motor off of the door I tested it with a 12 volt drill battery(pic4). It worked. But I couldn't figure out why it was working now and not before. Until I noticed the spring that is mounted just to the left of the motor on the door panel. I think the spring is tightened when the window is lowered, then it helps the motor lift the window up. Which explains why my window stopped working in the closed position, because the motor didn't have enough power to to lower the window and tighten the spring at the same time.
I put a new motor in by reversing the steps above and tested the window before I put the door panel back on. It works much faster and smoother than before.
