I have a 2001 Pontiac grand prix. My rear drivers side window wont roll up or down, When i took door panel off, i noticed a blue and red wire that has a gray plug, That seems to me should go somewhere, does anyone know where that somewhere might be?? thanks.

It says the tachometer wire is Yellow/Green, you do not have that listed. You will find it in the list below, it is highlighted..

The only way I know to get the window up is to remove the door panel and run the window motor with jumper wires. However, before you replace the switch (which is not usually the problem) you should check the wires on the driver's door between the point where the wires exit the door and enter the kick panel area. It's common for the wires and insulation to break down over the years, and since the driver's door is opened and closed the most, causing the wires to bend back and forth, it is a common failure. The passenger side window uses the wiring in the driver's side door to operate.

In my 2001 Grand prix it did the same thing and it was the switch. try replacing the switch.

I have had the same problem with my driver side window ,., it might go down but get stuck half way up and wouldn't go any further. take the door panel off and all the protective plastic , it goes back on easly enough, it might sound crazy but i took a bar of soap and soaps all the tracking where the window slides up and down and I sware it works better than my other window I mean it works better than when i bought it, try it you'll be glad you did

Sounds like the rod or cable disconnected from the inside lever, you have to take the door panel off and see what came loose.

You will have to remove the button cover with a flat tool such as a screw driver, and use alcohol with a cotton swab to clean the electrical contacts.

I had a problem similar to this but mine was in a GT and they would just work when they wanted to. I just had all the wires cut leading to the front passenger seat, back driver seat, and back passenger seat. And left the wires on the main. They all work perfect now. But the downside is that the driver is the only one who can put the windows down. (Which isn't always a bad thing) Hope I could help!

take the door panel off and block the window up with a peice of wood, yes that is how we do it.

if motor is running, probable cause is the window regulator

undo inner door panel to view the mechanism

plastic clip on back of handel , hard to remove without right tool , but can be done
