2001 Pontiac Grand Prix Question: Bad window motor or switch
If the window was slow and now does not work, then it is likely a faulty motor. The switch would be a "pass" or "fail" situation - not a slow operator. Do your lights dim when you try to roll it up? If so, it's a sign of excessive draw from the motor. One further suggestion - motors often get overworked by having to push the window on extremely dry and restrictive glass runs - the strips on the sides of the windows that guide the glass. Lubricate those on all windows regularly to reduce window motor drag and excessive wear. This could be what your issue is (although it may be a motor by now...)... - DaveJHM
