Driver Power Window Inoperative
- Ignition OFF, disconnect the X2 harness connector at the driver window switch.
- Test for less than 1 ohm between the ground circuit terminal A and ground.
- If greater than the specified range, test the ground circuit for an open/high resistance.
- Ignition ON, verify that a test lamp illuminates between the B+ circuit terminal H and ground.
- If the test lamp does not illuminate, test the B+ circuit for a short to ground or an open/high resistance.
- Verify that a test lamp illuminates between the ignition circuit terminal G and ground.
- If the test lamp does not illuminate, test the ignition circuit for a short to ground or an open/high resistance
- Connect the X2 harness connector at the driver window switch. Disconnect the harness connector at the driver window motor.
- Test for less than 1 ohm between the control circuit terminal listed below and ground.
- If greater than the specified range, test the control circuit for a short to voltage or an open/high resistance. If the circuit tests normal, replace the driver window switch.
- Connect a test lamp between the control circuit terminal A and control circuit terminal B.
- Command the driver window UP and DOWN by using the driver window switch. The test lamp should illuminate when commanding the UP and DOWN states.
- If the test lamp remains OFF during either of the commands, test either control circuit for a short to ground. If the circuits test normal, replace the driver window switch.
- If all circuits test normal, test or replace the driver window motor.
