What should I do if the plastic door of the rear fender doesn't close tightly?

Check the door lock, adjust the door, replace the door and check the door panel.

1. Check the door lock: Check whether the door lock is normal. If there is something wrong with the door lock, it needs to be repaired or replaced.

2. Adjust the door: Try to adjust the door and check whether the fixing screws of the door are loose. If it is loose, it needs to be tightened again.

3. Replace the door: the door cannot be adjusted and needs to be replaced.

4. Check the door panel: Check whether the door panel is deformed or damaged, and the damaged door panel needs to be repaired or replaced.
