Power Window System



Diagnosis & Testing

The window glass must be free to slide up and down for the power window motor to function properly. If the glass is not free to move up and down, the motor will overload and trip the integral circuit breaker. To determine if the glass is free, disconnect the regulator from the glass. Then slide the window up and down by hand.

There is an alternate method to check if the glass is free. Position the glass between the up and down stops. Then, shake the glass in the door. Check that the glass can be moved slightly from side to side, front to rear, and up and down. Then check that the glass is not bound tight in the tracks. If the glass is free, proceed with the diagnosis that follows. If the glass is not free, determine the cause of the condition.

If the only inoperative window is in the driver or passenger side front door and the preceding checks have not identified a problem, check the window motor using the following procedure:

  1. Disconnect and isolate the battery negative cable. Remove the trim panel from the door with the inoperative power window.
  2.  
  3. Unplug the power window motor wire harness connector. Apply 12 volts across the motor terminals to check its operation in one direction. Reverse the connections across the motor terminals to check the operation in the other direction. If the window is in the full up or full down position, the motor will not operate in that direction by design. If OK, repair the circuits from the power window motor to the power window switch as required. If not OK, replace the inoperative motor.
  4.  
  5. If the motor operates in both directions, check the operation of the window glass and lift mechanism through its complete up and down travel. There should be no binding or sticking of the window glass or lift mechanism through the entire travel range. If not OK, check the window glass, tracks, and regulator for sticking, binding, or improper adjustment.
  6.  

If the problem being diagnosed involves only the Auto-down feature for the driver side front door window, but all of the power windows are operational, replace the driver's side window/lock switch.

For a rear power window problem proceed with the following:

  1. Disconnect and isolate the battery negative cable. Unplug the wire harness connector from the power window switch unit on the door with the inoperative power window. Check for continuity between the ground circuit cavity of the power window switch wire harness connector and a good ground. There should be continuity. If OK, go to Step No. 2. If not OK, repair the open circuit to the power window and door lock master switch as required.
  2.  
  3. Connect the battery negative cable. Turn the ignition switch to the On position. Check for battery voltage at the fused ignition switch output (run) circuit cavity in the body half of the power window switch unit wire harness connector. If OK, go to Step No. 3. If not OK, repair the open circuit to the power window and door lock master switch as required.
  4.  
  5. Test the power window switch continuity. If OK, go to Step No. 4. If not OK, replace the power window switch.
  6.  
  7. Check the continuity in each circuit between the inoperative power window switch wire harness connector cavities and the corresponding power window motor wire harness connector cavities. If OK, refer to the above procedure to check window motor. If not OK, repair the open circuit(s) as required.
  8.  

If all windows are inoperative, proceed with the following:

  1. Check the circuit breaker. If OK, go to Step No. 2. If not OK, replace the inoperative circuit breaker.
  2.  
  3. Disconnect and isolate the battery negative cable. Remove the window/lock switch from the driver side front door trim panel. Unplug the wire harness connector.
  4.  
  5. Check for continuity between the ground circuit cavity of the door module wire harness connector and a good ground. If OK, go to Step No. 4. If not OK, repair the circuit to ground as required.
  6.  
  7. Connect the battery negative cable. Turn the ignition switch to the On position. Check for battery voltage at the fused ignition switch output (run) circuit cavity of the window/lock switch wire harness connector. If OK, refer to Diagnosis and Testing of Power Door Locks. If not OK, repair the circuit as required.
