What is the reason why the A4L rearview mirror cannot open automatically?
1 Answers
The following are related solutions for the A4L rearview mirror not opening automatically: 1. Test the rearview mirror's operation: Have someone assist by operating the rearview mirror switch inside the car while you place your hand on the mirror to feel if the motor inside is working; 2. Gear damage: If you feel the motor's vibration but the mirror does not move, it indicates that the opening/closing gear mechanism is damaged; 3. Motor failure or wiring issue: If you do not feel the motor's vibration, even after tapping it a few times, it suggests a motor failure or wiring problem, with wiring issues typically being a damaged switch or a blown fuse. 4. Check the fuse and switch: First, inspect the fuse for the rearview mirror folding circuit. If the fuse is fine, the issue is likely a faulty switch. Sometimes, extremely low temperatures or dust buildup in the extension mechanism can increase resistance, preventing the mirror from opening. In such cases, manually assisting the mirror to open might help resolve the issue.
