I have a 04 trailblazer. The power window buttons on the drivers side door do not work. The window lock button works and the door lock button works. All I can think is the motor is shot. Any thoughts?
Have you checked the fuses? After that, you need to pull the door panel off and check for voltage at the switch and the motor. The electrical plug to the motor should be removable without pulling the motor. This should give you a better idea of what is wrong before buying a replacement motor.
