- Ignition OFF, disconnect the X2 harness connector at the driver window switch.
- Test for less than 1 ohm between the ground circuit terminal B 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 ignition circuit terminal E and ground.
- If the test lamp does not illuminate, test the ignition circuit for a short to ground or an open/high resistance.
- Ignition OFF, connect the harness connector at the driver window switch and disconnect the harness connector at the driver window motor.
- Test for less than 1 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 the circuit tests normal, test or replace the driver window switch.
- Test for less than 1 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 the circuit tests normal, test or replace the driver window switch.
- Connect a test lamp between the control circuit terminal A and control circuit terminal B.
- Ignition ON, command the driver door 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 does not illuminate during either of the commands, test both control circuits for a short to ground. If the circuits test normal, test or replace the driver window switch.

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.
