Power Window Motor

NOTE: Before performing power window motor test, ensure power window switch is functioning properly. Window glass must be free to slide up and down for power window motor to function properly. If glass does not move freely, motor will overload and trip circuit breaker.

NOTE: If power window is in full up or full down position, motor will not operate in that direction by design.

Turn ignition switch to OFF position. Disconnect negative battery cable. Remove door trim panel of suspect power window motor. See DOOR TRIM PANEL under REMOVAL & INSTALLATION. Disconnect suspect power window motor harness connector. Using a 12-volt power source, connect 12-volts to one terminal of power window motor harness connector. Power window motor should operate. Reverse 12-volt power source connection at power window motor harness connector. Power window motor should operate in opposite direction. If power window motor operates as specified, check wiring harness between power window switch and power window motor. See WIRING DIAGRAMS . Check power window travel through complete opening and closing cycle. Check power window for sticking, binding or improper adjustment. If power window travel is not as specified, repair as necessary.
