Repair Instructions

1. Remove the Door Panel

Step 1: Disconnect the battery to prevent any electrical shorts.
Step 2: Use the trim removal tool to carefully pry off the window switch bezel.
Step 3: Remove screws securing the door panel (usually a combination of Phillips screws).
Step 4: Carefully detach the door panel from the clips by pulling it away from the door.
Step 5: Disconnect any electrical connectors for the switches and speakers.

2. Access the Window Motor

Step 1: Locate the window motor at the bottom of the door frame.
Step 2: Remove any additional screws or bolts securing the motor to the door frame using a 10mm socket wrench.
Step 3: Detach the wiring harness from the motor by squeezing the clip and pulling it off.

3. Test or Replace the Window Motor

Step 1: If the motor is unresponsive when powered directly, it may need replacement.
Step 2: Install the new motor by reversing the removal steps, ensuring that screws are secured tightly.
Step 3: Reconnect the wiring harness to the new motor.

4. Reassemble the Door

Step 1: Reattach the door panel by connecting all necessary electrical connectors.
Step 2: Press the door panel back into place, ensuring all clips are seated correctly.
Step 3: Replace all the screws that were removed.

5. Final Testing

Step 2: Test the window operation using both the driver's switch and the individual window switch.
Step 3: Ensure the one-touch feature is functioning properly.

Conclusion

If after following these steps the power window still does not operate correctly, further diagnosis may be required. This could involve checking the Body Control Module (BCM) or consulting with a professional technician for advanced diagnostics.
