One Window Inoperative
NOTE:
Window glass must be free to slide up and down for power window motor to function properly. If glass is not free to move up and down, motor will overload and trip circuit breaker.
- Place window glass halfway between up and down positions. Verify glass can be moved slightly from side to side, front to rear, and up and down. If glass does not move freely, adjust glass or repair as necessary. If glass moves freely, go to next step.
- Test driver's power window switch. See DOOR MODULE under COMPONENT TESTS. If power window switch is not okay, replace Driver's Door Module (DDM). If power window switch is okay and driver's door window is inoperative, see POWER WINDOW MOTOR under COMPONENT TESTS. If power window switch is okay and any other window is inoperative besides driver's window, go to next step.
- Check continuity of each circuit between inoperative Passenger's Door Module (PDM) or rear power window switch harness connector and corresponding DDM harness connector terminal. See WIRING DIAGRAMS . See Figure -Fig 2 . If continuity exists in all circuits, repair power window motor. See POWER WINDOW MOTOR under COMPONENT TESTS. If continuity does not exist in any circuit, repair open in appropriate circuit(s).
