While this metal gear is physically suitable for the application, it cannot be used with the factory mirror motor. It creates a grounding problem that could damage the vehicle's electronics. Therefore we recommend that when replacing this metal gear, please take grounding measures to protect the motor. Solve the electronic mirror not folding due to damage of plastic gear. Since gear is plastic material which is consumable part ,it is easy to collapse because of frequent use, which lead to the electronic mirror can not be used normally, if you go to repair store you can only replace the assembly or the whole part which cost very high!
