If your motor is functioning properly but the window is not responding, you may need to replace your regulator. Remove the bolts that attach the regulator to the glass. The regulator is the lift assembly that moves your window up and down. You will have to move the window up or down to align these bolts with a hole in the door interior. Using an extension on a ratchet, you will put a socket (usually 8 or 10 mm) through the hole and loosen the two bolts. Push the window all the way up. Use your hands to push the window up, and then either fasten it with tape or pull it out of the door altogether.
If belt tension is correct, then the next item to check is the alternator itself. You now have two choices - you can test the alternator yourself with a simple test using a voltmeter, or you can have the test performed by a professional. If you choose to do the test yourself, then you will need a DC voltmeter, or a multimeter. Such a unit can be purchased at most auto supply stores, hardware stores, department stores, home improvement stores, etc.
