Identifying Common Chevrolet Tahoe Mirror Problems and Their Causes

The Chevrolet Tahoe is part of General Motors' full-sized SUV family. Probably because of its huge built and stable stance, the Chevy Tahoe became one of North America's most favorite GM vehicles. Aside from its superior engine and stylish body, the Chevrolet Tahoe also boasts of its world-class safety features that guarantee the drivers' comfort and safety while on the road. Take for instance its top-notch mirror assembly. The Tahoe's side- and rear-view mirrors are equipped with additional features, which are designed to improve the owner's driving experience. However, due to some unavoidable circumstances, the Tahoe's mirrors and their extra features tend to malfunction and fail. Here are the most common problems encountered by Chevrolet Tahoe mirror assembly and the reasons behind them:

Power-folding mirrors won't fold in/out

Chevrolet Tahoe usually has power-folding side-view mirrors, which allow the owner to fold the mirror and its cover in and out by pushing a control switch near the steering wheel. However, many Chevrolet Tahoe owners complain about their mirrors' inability to fold in and/or out automatically when they push the switch. If the mirrors won't fold in AND out, you may want to check for a blown-up or burnt fuse. Checking the motor for any damage may also do the trick. But if the malfunction only happens to the "folding in" aspect of the feature, it is advisable to clean the wiring harness as well as the control switch and check if they are loose or broken.

Power-adjustment feature is not working

Aside from power folding, Chevrolet Tahoe mirrors also have a power-adjustment feature that makes it possible for the driver to adjust the angle and coverage of the side- and rear-view mirrors according to his driving preferences. Over time, this feature has the tendency to deteriorate and fail. This failure may be caused by a busted mirror assembly fuse, loose or burnt electrical connections, or a broken control switch. Either way, this problem can still be solved easily by replacing the damaged mirror assembly component.

Heated mirrors won't defrost

Some Chevrolet Tahoe mirrors have heating abilities, which prevent them from freezing during winter. If your heated mirrors are not performing their duties well, you may want to check the heater motor or its switch. The heater motor is prone to rust accumulation since it is exposed to harmful elements on a regular basis. Another possible reason behind its failure is inactivity. Sometimes, heater motors deteriorate fast when they are seldom used. Aside from the motor, the heated mirrors' sensor can also cause the heating feature to fail. If the sensor can no longer determine the temperature accurately, the heater won't be able to activate in time. Other possible causes include faulty wiring harness and busted fuse.
