Because the window probably jumped the track or the track has become disconnected somehow. Pull the door panel off and you should easily be able to determine what it is and fix it. well the motor is connected with some belt or any other thing to move the window may be that belt got sliped from motor or broken due to this motor is running freely.
Yes, you can manually put up a power window in a 1997 Pontiac Grand Prix if the power mechanism fails. You would need to remove the door panel to access the window motor and regulator. By manually turning the motor or using a tool to lift the window, you can raise it. However, it's advisable to fix the electrical issue or replace the power window components for a permanent solution.
Salvage yard would be an inexpensive choice.
Its possible you:ve blown a fuse, I would check them first.could also be window motor or your main window control
the window motor might be bad or there is not of power in your cords to power it
Check your fuses, check for power going into the window motor, exc.
the motor and the switch both work but the window will not move
It is possible that the power window motor and the blower motor are both faulty or that you have faulty wiring.
There is no single fuse for one power window. The most common thing is the switch to fail. This would be the master window switch. Try jumping the wires with a live current and see if the window goes up and down. If it does then its your switch, if the motor fails to move most likely its the motor/regulator.
I would suspect an intermittent short in the wiring to the power window motor in the section between the door and the door jam.
A power window that goes down but not up in a Pontiac Transport could indicate a problem with the window motor or the regulator, as these components are responsible for the window's movement in both directions. It may also be caused by a faulty switch or wiring issue, preventing the up command from reaching the motor. Another possibility is a blown fuse related to the window's power supply. Diagnosing the issue would require checking these components systematically.
Cause the window motor is out
If the passenger side works fine and there is no power at the driver side motor, I would suspect the switch. A weak motor will overheat the switch causing it to melt inside where the contacts are.
