Common Signs of a Defective Hyundai Mirror
Vehicle mirrors are important factors for safe driving and parking. When your Hyundai mirror does not function as it should, it will be difficult and dangerous to maneuver your vehicle.
Here are some common signs of a defective mirror, plus a couple of troubleshooting tips:
Electronic displays not working
One of the most obvious signs of a defective mirror can be seen on the mirror itself. Usually, auto dimming rear view mirrors have built-in electronic features such as time, temperature, and travel signals. If the features are not displayed in your Hyundai mirror, the wiring or mirror itself may be damaged. Alternatively, if the features are visible but are working intermittently, there may be problems with the connections.
Added features are working except the main function
It is quite common for vehicle mirrors to have other features such as the heating function added with built-in defroster or the auto dimming control integrated with time, temperature, and signal features. However, if all the added features are working properly but the main function isn't, you should start checking your sensors.
You can find the sensors at the back of your Hyundai mirror. Make sure to clean them properly to rid them of dust or snow. For some features such as the auto dimming, if the dimmer still does not function even with a light shown from the vehicle's rear, your window tint may be the problem. Some vehicles are fitted with factory tinting on the windows, and if you add another aftermarket tint to the rear window, your auto dimming mirror will be affected. You can test this by shining a light on the mirror from inside the vehicle.
Display features work irregularly
For a Hyundai mirror with a dimming function, a loose connection or short circuits can cause various issues on the rear view mirror. You may notice that sometimes, it works just fine but then on other days, some features may not work at all. You can use a voltmeter to check the wiring and look into any fluctuation in the current.
Mirror control not working properly
Other than the sensors found outside your rear view mirror, you can also control the mirror function such as dimming using a trigger inside. If the trigger does not function as it should, the mirror will not dim when necessary. You can use a voltmeter to test the wiring and find out if such trigger is the culprit for your mirror problems.
Other troubleshooting tips
For some vehicles fitted with heaters on their mirrors, they won't function properly unless their rear defrosters are working. You can use these defrosters to melt ice off the mirror.
