- Ignition OFF, disconnect the harness connector at the appropriate front window motor.
- Test for less than 1.0 ohm between the control circuit terminal A and ground.
- If greater than the specified range, test the control circuit for a short to voltage or an open/high resistance. If circuits test normal, replace the door module.
- Test for less than 1.0 ohm between the control circuit terminal B and ground.
- If greater than the specified range, test the control circuit for a short to voltage or an open/high resistance. If circuits test normal, replace the door module.
- Connect a test lamp between the control circuit terminal A and the control circuit terminal B.
- Ignition ON, command the window UP and DOWN by using the 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. If the circuits test normal, replace the door module.
