What is the reason for the sudden failure of the automatic folding function of the Mercedes-Benz car's rearview mirror?
2 Answers
The electric folding function of the exterior rearview mirror fails. Excluding mechanical and electronic control reasons, the causes for the Mercedes-Benz rearview mirror not folding automatically are: 1. The battery is disconnected or dead: In this case, the exterior rearview mirror must be reset to function properly. The specific reset method is to manually operate the folding button. 2. After setting "fold the rearview mirror when locking the car," you manually folded it: In this situation, the exterior rearview mirror will not automatically unfold the next time you unlock the vehicle. You need to enter the car and press the button on the door to manually unfold the exterior rearview mirror.
My Mercedes also had this issue with the rearview mirror, which I believe was caused by an electrical system malfunction. Common problems include blown fuses—these are small circuit protection devices that melt in case of short circuits or overloads to prevent greater damage; aging wiring or poor contact may also lead to signal interruptions, and if the control module fails, the entire function becomes inoperative; another possibility is power supply issues, such as a dead battery—though the lights may still work, high-power motors won't start. Regular checks of the fuse box and replacing old parts are advisable. Mercedes' electronic systems are complex, so avoid DIY repairs to prevent further complications. Safe driving is crucial—if the mirror gets stuck while folding and affects parking, visit a professional repair shop immediately.
