Repair Instructions

Step 1: Remove the Door Panel

Inspect the Motor:
- Check for any physical damage or disconnections.
- If necessary, disconnect the motor from its power source.
Test the Motor:
- Using a multimeter, check for power at the motor connector when the switch is activated.
- If there is power and the motor does not operate, the motor is likely faulty and needs replacement.

Step 3: Replace the Window Motor (if necessary)

Remove the Old Motor:
- Unscrew the motor from its mount.
- Carefully detach any linkages connecting the motor to the window regulator.
Install the New Motor:
- Position the new motor and connect it to the window regulator.
- Secure it in place with screws.
Reconnect Power:

Step 4: Reassemble the Door Panel

Reconnect Electrical Connectors:
- Reattach any connectors you previously disconnected.
Reinstall the Door Panel:
- Align the door panel with the door frame and press it firmly to engage the clips.
- Replace screws in their original locations.
Reattach Trim Pieces:
- Snap or screw back any trim pieces you removed.
Reconnect the Battery:
- Reconnect the negative terminal to restore power.

Step 5: Final Testing

Test the window operation using both the driver’s switch and the individual switch to ensure proper functionality.
Observe for any unusual sounds or movements.
