Tools Required

Multimeter
Fuse puller or needle-nose pliers
Screwdrivers (Phillips and flathead)
Panel removal tools
12V power supply (such as a jump starter or car battery)

Repair Instructions

Remove the Door Panel:
- Disconnect the negative battery terminal to ensure safety.
- Use a panel removal tool to carefully pry off the door panel clips and remove screws securing the door panel (usually located around the handle and edges).

Test or Replace the Window Motor:
- If the motor does not operate when connected directly to power, it may need replacement.
- To replace the motor, unbolt it from the regulator assembly and remove it.
- Install the new motor in reverse order of removal, ensuring it is securely mounted.
Reassemble the Door Panel:
- Reconnect the wiring harness to the new motor.
- Test the window operation before fully reassembling the door panel.
- Once confirmed, reattach the door panel, aligning the clips and securing screws.
- Reconnect the battery terminal.
Final Testing:
- Test the window operation multiple times to ensure everything is functioning properly.
- Check for any abnormal noises or resistance during operation.
