i had the same problem with my integ. it worked completely fine before right? then all of a sudden it doesnt work? check the wiring from the door to the body of the car...hold the harness and wiggle it around while you push the switch up with your other hand. it worked it for me...maybe it might work for you too. if that doesnt work maybe the brushes on your pw motor is dirty. first try taking a mallet and give it some good taps while you play with the switch...if that doesnt work try taking the motor out and throwing it against the wall a few times...or you could just do it the easy way and get a dvom and test for power to the motor...it should read batt voltage.
