I am working on the drivers door window of a 1994 Corvette C4 coupe. Having dufficulty lining window in the closed position. Front of glass rides up in the up position. There is no adjustment to counter this action. Is there something I'm missing that should prevent this? By the way, new window guides have been installed.

Edward,

C4 Corvettes have an Outside Air Temperature sensor which may be faulty. It senses air temp in front of the car and tells the climate control unit (which controls the heat/ac) what the temp outside is. Yours is in front of the grill. It's a $20 part. It looks like the attached link. I'm not sure if this is your issue, but it was on my son's car. I just thought it might give you a direction to check.

This may be as simple as relearning the window stop positions. Perform the following procedure to relearn the windows;

1) Sit in the drivers seat and ensure both doors are fully closed.
2) Turn the key to the ON position but do not start the vehicle.
3) Pull up on the drivers window switch until the window reaches the full up position, then CONTINUE HOLDING THE SWITCH UP for 2-5 seconds, then release the switch.
4) Push down on the drivers window switch until the window fully opens, then CONTINUE HOLDING THE SWITCH DOWN for 2-5 seconds, then release the switch.
5) Repeat steps 1-4 for the passenger window.
6) Close both windows and check the operation of the smart glass.

Let me know if you need further help.

new window regulator probably. theres an electric motor that has a gear that rides along a curved piece of metal with teeth on it, thats how it raises/lowers the window and the teeth at the end are probably worn. I believe only the coupes use the gear driven setup and the sedans use cables, but I am not 100% sure of that fact, but I do know for sure that the coupes use the gear driven setup.

Hope this helps.

If the motor is working but the glass is not moving something must have broke inside the door. See if you can sneak a piece of duct tape down along side the glass, get it down as far as possible. Use a butter knife or something to make the tape stick to the glass, now try pulling the glass up with the tape. You may want run the window motor at the same time maybe it will catch. If you get the window up, tape it with duct tape so you can get it to a shop to get it fixed. Good luck.

Does it go all the way up when door open, then close it and seals good?

you either need a motor or motor and window regulator assembly.
