What is the reason for the Volkswagen rearview mirror heating not working?
2 Answers
Volkswagen rearview mirror heating not working is mostly a symptom of the car's electric heating function. Here are the detailed reasons and solutions for Volkswagen rearview mirror heating not working: 1. The electric heating function of the car's rearview mirror is not activated. Solution: Press the heating button and wait for a while, then touch the rearview mirror with your hand to see if it feels warm. If it does, it means the circuit is fine. 2. Insufficient car battery power. Solution: Replace the battery or charge the battery. 3. The rearview mirror heating switch is damaged. Solution: Go to a 4S store for replacement.
I've been driving for several years and have encountered similar issues. When the rearview mirror heating on a Volkswagen doesn't respond, common causes include a blown fuse or wiring problems. Last week when I checked, I first looked at the fuse box on the main console—some positions are clearly labeled, and replacing a fuse might solve the problem; sometimes it's a simple fix. The heating element could also be aging or short-circuited, especially during humid seasons when issues are more likely to arise. Poor contact in the switch button is also quite common—if pressing it a few times doesn't work, it's time to check the internal wiring. I'd recommend regularly cleaning the rearview mirror to prevent rust, as the heating function is extremely useful during rain or frost, significantly improving driving safety. If DIY attempts don't resolve the issue, head to a professional repair shop—don't delay, as poor visibility can be very dangerous.
