i have a convertible 02 gt and i have a window problem. the driver side main window will not roll up or down. i have replaced the switch and it didnt help. I have also taken the panl off and jumped the motor and it will work fine, so im thinking it could be the AutoDown mechanism thats holding it.

Anyways, is there a detailed wiring schematic somewhere other then whats in the normal chiltons/haynes manual? they are not very good.

Replacing parts just to see if it fixes the problem is a common way to waste money. Get yourself a multimeter and back track to where you are geting voltage. If you can find where your voltage disapears you will find your problem. Have you checked your fuses ?

I think you are right about the autodown. Power to the driver's window is routed through the GEM (generic electronics module, located near the underdash fuse panel). If the relay in the GEM has failed, you won't be able to raise or lower the window, but the other three will work OK.

GEM failures are rare; perhaps a connector fell off. Did you do any electrical or interior repairs just before the window stopped working? Are other GEM functions working OK (such as trunk light timer, map lights timer, intermittent wipers)?

If you leave your door open does the dome light shut itself off after a few minutes or does it just stay on forever ? Also, if you open your drivers door and then shut it, does it wait about 20-30 seconds before the dome light shuts off ?

If you are desperate to get the window working, and are willing to sacrifice the "auto down" feature for now, it is possible to bypass the GEM with a jumper installed behind the door panel. I can describe how to locate the 2 wires if you want to try this. It involves cutting 2 wires and splicing them together. The wiring could later be restored to factory original with 2 insulated crimp splices.

I posted the '01 schematic at: http://members.cox.net/n0v8or/01_pwr_windows.jpg
Hopefully, there were no changes from 2001 to 2002.

There are 2 white-with-black-stripe wires connecting to the window motor.
Identify which of these connects directly to the window switch. The other goes to the GEM and is the one to cut (labeled #226).
The second wire to cut is tan / blue stripe, and is connected to the window switch connector.

Now, run a jumper wire between the white/black wire that goes to the motor, and the tan/blue wire the goes to the window switch connector. Ordinary plastic wire nuts are OK to make the connections. Jumper wire size should be similar to the factory wires.

This connection allows the window switch to operate the motor directly. Temporarily plug the connector into the switch and test before replacing the door panel.
