1. Driver Window Malfunction

2. Passenger Window Malfunction

3. Rear Windows Malfunction

Circuit/System Description

When the ignition switch is in the RUN or ACCY position, or retained accessory power (RAP) is enabled and the driver or passenger window switch is pressed in the down position, voltage is applied to the appropriate window motor causing that window to open. When the driver or passenger window switch is pulled in the up position, voltage is applied to the appropriate window motor in the opposite direction causing that window to close.

The driver master control contains a rear window lockout switch which disconnects the battery positive voltage supply to both rear passenger door window switches, disabling them. The RR and LR window switches on the driver master control will continue to function normally.

1. Driver Window Malfunction

2. Passenger Window Malfunction

3. Rear Window Malfunction

Circuit/System Description

The front power windows are controlled by the driver window switch and the front passenger window switch. The driver window switch contains the master power window switch that controls all power window operations. When a power window switch is activated to a desired position, power window switch will send a signal to its respective door window motor to move the window to the desired position. The window motors will also receive a signal from the body control module (BCM) to globally express down while lowering the hardtop.

The window indexing feature is used to lower the driver and passenger power windows approximately 4 mm when the door is opened. This is necessary to allow the top edge of the window to clear the window weather-strip. This feature will also raise the window to the fully seated position once the door is closed.

    2. ⇒If the driver window does not perform the UP/DOWN function, refer to Driver Window Malfunction.
  2. Command the passenger window UP and DOWN using the RF window switch on the driver master control and the passenger door window switch. The passenger window should perform the UP and DOWN functions from each switch.
    3. ⇒If the passenger window does not perform the UP/DOWN function, refer to Passenger Window Malfunction.
  3. Command the express up and express down functions of the driver and passenger door windows by pressing their window switches past the first detent and releasing and pulling their window switches past the first detent and releasing. The appropriate window should perform the express up and express down function.
    4. ⇒If the function does not perform as specified, refer to Power Window Reinitialization .

  7. Ignition OFF, connect the harness connector at the passenger window switch and disconnect the harness connector at the passenger window motor.
  8. Test for less than 1 ohm between the ground circuit terminal 4 and ground.
    9. ⇒If greater than the specified range, test the ground circuit for an open/high resistance.
  9. Ignition ON, verify that a test lamp illuminates between the B+ circuit terminal 6 and ground.
    10. ⇒If the test lamp does not illuminate, test the B+ circuit for a short to ground or an open/high resistance. If the circuit tests normal and the PWR WDO fuse is open, replace the passenger window motor.
  10. Connect a test lamp between the control circuit terminal 1 and ground.
  11. Command the passenger window DOWN by using the passenger window switch. The test lamp should illuminate when commanding the DOWN state.
    12. ⇒If the test lamp does not illuminate, test the control circuit for a short to ground. If the circuits test normal, test or replace the passenger window switch.
  12. Connect a test lamp between the control circuit terminal 2 and ground.
  13. Command the passenger window UP by using the passenger window switch. The test lamp should illuminate when commanding the UP state.
    14. ⇒If the test lamp does not illuminate, test the control circuit for a short to ground. If the circuit tests normal, test or replace the passenger window switch.
  14. If all circuits test normal, replace the passenger window motor.

Component Testing

Driver Window Switch
