Rear Passenger Window Malfunction

  1. Ignition OFF, disconnect the harness connector at the appropriate rear window switch.
  2. Test for less than 1 ohm between the ground circuit terminal E and ground.
    • If greater than the specified range, test the ground circuit for an open/high resistance.
  3. Ignition ON, verify that a test lamp illuminates between the B+ circuit terminal A and ground.
    • If the test lamp does not illuminate, test the B+ circuit for a short to ground or an open/high resistance.
  4. Enable the rear windows by using the window lockout switch on the driver master control.
  5. Test for greater than 10 volts between the control circuit terminal D and ground.
    • If less than the specified range, test the control circuit for a short to ground or open/high resistance. If the circuit tests normal, replace the BCM.
  6. Connect a test lamp between the signal circuit terminal B and B+.
  7. Command the rear window DOWN with a scan tool. The test lamp should illuminate during the DOWN command.
    • If the test lamp does not illuminate, test the signal circuit for a short to voltage or open/high resistance. If the circuits test normal, replace the BCM.
    • If the test lamp continuously illuminates, test the signal circuit for a short to ground. If the circuit tests normal, replace the BCM.
  8. Connect a test lamp between the signal circuit terminal C and B+.
  9. Command the rear window UP with a scan tool, the test lamp should illuminate during the UP command.
    • If the test lamp does not illuminate, test the signal circuit for a short to voltage or open/high resistance. If the circuits test normal, replace the BCM.
    • If the test lamp continuously illuminates, test the signal circuit for a short to ground. If the circuit tests normal, replace the BCM.
  10. Ignition OFF, connect the harness connector at the rear window switch and disconnect the harness connector at the rear window motor.
  11. Connect a test lamp between the control circuit terminal A and control circuit terminal B.
  12. Ignition ON, command the rear window UP and DOWN by using the rear window switch. The test lamp should illuminate when commanding the UP and DOWN states.
    • If the test lamp is always OFF during either of the commands, test either control circuit for a short to ground or open/high resistance. If the circuits test normal, replace the rear window switch.
    • If the test lamp is always ON, test either control circuit for a short to voltage. If the circuits test normal, replace the rear window switch.
  13. If all circuits test normal, test or replace the rear window motor.

When to See a Mechanic

Stop DIY work and contact a certified mechanic immediately if any of the following apply:

  • • You smell fuel, burning insulation, or see smoke.
  • • Brakes feel soft, pull hard to one side, or make grinding noises.
  • • The engine overheats, stalls repeatedly, or misfires under load.
  • • You are missing required tools, torque specs, or safe lifting equipment.
  • • You are not confident in the next step or safety outcome.
