Although this metal gear is physically suitable for the application, it cannot be used with the factory mirror motor. This creates a grounding problem that could damage the vehicle's electronics. Therefore, we recommend taking grounding measures to protect the motor when replacing this metal gear. Solve the electronic mirror that does not turn due to a damaged plastic gear. Since the gear is a plastic material that is a consumable part, it is easy to break down due to frequent use, which leads to the electronic mirror cannot be used normally. If you go to a repair shop, you can only replace the whole set or the whole part, which cost a lot!
