What is the reason for the continuous rotation of the rearview mirror folding motor?

It may be due to a switch issue or a circuit short. Common faults of electric rearview mirrors: When the electric rearview mirrors do not work at all, or only some functions are abnormal, the troubleshooting methods are as follows. If the electric rearview mirrors do not work at all, first check the fuse or power lines for open or short circuits, then inspect the control switch for damage or loose connections. If some functions of the electric rearview mirrors are abnormal, focus on checking the wiring connections and whether the electric rearview mirror switch or motor is functioning properly. The middle position of the car's electric rearview mirror control is: The button for adjusting the exterior rearview mirrors electrically, when placed in the L position, means you can now adjust the left exterior mirror. Placing it in the R position allows adjustment of the right side. If placed in the middle, it cannot be adjusted. There should also be a joystick or front/back/left/right buttons for adjustment. The location varies by brand—some are placed on the driver's side door armrest, some below the air vent on the left side of the steering wheel, and some near the gear shift position.
I've been driving for over twenty years and have seen many cases where the power folding mirror motor keeps running. The root cause is often the control module, which sends incorrect signals causing the motor not to stop; additionally, gear jamming or dust buildup can make the motor keep trying to turn while the mirror remains stuck. Switch failures may also get stuck in the 'fold' position, keeping the system powered. Wiring shorts, such as from aging connectors or water seepage, can also cause loss of control. I recommend turning off the power immediately to prevent overheating and component damage. Regular cleaning of the bracket and applying lubricant can effectively avoid this issue. Some car models have design flaws that make them prone to this problem, and experienced owners share that replacing the motor module solves it—but don’t delay, as it poses significant safety risks.
My car repair experience tells me that when the side mirror folding motor keeps spinning non-stop, it's often a sign of mechanical jamming. Worn gearboxes or dust buildup can cause the gears to lock up, making the motor struggle to turn. Rusted or deformed hinges increase resistance, yet the system keeps supplying power. Other issues include insufficient lubrication causing high friction, or freezing in winter leading to jams. I've observed similar cases and found that a DIY solution is to disconnect power, clean the bracket, and add lubricant to reduce load. Ignoring it long-term can overheat and burn out the motor, even damaging other components. Timely inspection and professional repair when needed are crucial. Regular waterproofing during car washes can prevent such issues.
