Angry Window won't go up.....help!

Hey Corral....

I just bought a 96' GT and am having problems with the driver side window.
It goes down just fine, it went up twice..once lastnight and one more time earlier this evening; but now I cannot get it to go up at all.

I can hear the relay click when I press the switch for the window to go down, but I hear nothing when I click the switch for it to go up. The switch itself seems to be ok, but I really have no idea...

Any help would be greatly appreciated...anyone know how much a relay and/or switch goes for?

Thanks in advance!

First, are you aware that the Mustang's power windows are protected by an automatic reset circuit breaker in the engine bay and also in the window motor itself? This could explain why it works sometimes and not others. IE the CB trips when overheated and then resets once cool.

If this were my car, I would focus on the window motor first. Check for binding or anything that would cause the motor to use more power than it should. Run the window motor directly from battery. Test both up and down. This will also help narrow down between a motor problem or a switch problem.

I just replaced my pass side motor and regulator assy. It would not go up or down but dimmed the light when the button was pushed. I assume the motor was toast, new unit cost me about $60 shipped and not too hard to install but u do need a extra hand.

Hey guys, Thanks for the help!

The switch is ok, I swapped it with the pass-side one and it still did the same thing. When the motor does work it doesn't bind or dim the lights, sounds healthy as well.
Looks like some of the connections have been corroded due to a leaky a-pillar panel. I am going to clean them up and add some di-electric grease and see if that makes a change.

Do you know what the box bolted to the inside of the door panel is for? Could this be a problem? (connects to the window harness)

Blackbeast98: Do you just need someone to hold the window up? How did the motor come out?

Thank you!!

The black box is a one touch relay module, touch the drivers side window switch once and the window travels all the way down on its own. If the box is bad, your window motor will not go up or down, you should use a multimeter to see if your getting proper voltages. Motors are also a common problem, the gears strip out. You can buy replacement gears in the HELP section of the local auto stores, cost about 5 dollars per motor to fix and they normally work as good as new.

Quick and easy. Back probe the connector AT THE WINDOW MOTOR with a test light. Push the window switch to verify power. Verify power both ways on the switch, up and down(requires back probing each wire). If you have fire both ways, replace the motor. If not, you either have a bad switch or broken wire/connection somewhere along the harness.
