Shortcomings of a GMC Yukon Denali Mirror
Every driver needs an extra pair of eyes on the road. Whether you need help in seeing oncoming vehicles from a blind spot or backing up on the driveway, your GMC Yukon Denali XL mirror will give you a visual of what to expect on the road. Unfortunately, your vehicle's mirror are susceptible to a lot of wear and tear. If you encounter a problem on your SUV's mirrors, it's best to find out its cause before the issue becomes worse. Here are some of the problems that you might encounter:
Power mirrors won't retract
Mirrors that refuse to retract are usually an indication of a power mirror fuse failure. You need to replace the fuse if it is blown. If the fuse is not the problem, you can also check the mirror motor mechanism. A replacement will also be needed if the motor is defective-that is, if you hear a humming sound when mirror control switch is turned on.
Shorted wires in electric mirrors
Behind every electric mirror are wires that power up the assembly. Sometimes, these electric wires become shorted, and that affects the performance of your electric mirror. You can use a test light to check if there is any voltage coming from the wires. If no voltage is observed, that means the wires are shorted and need to be replaced.
Scratches and cracks on the mirror lens
You need to have a clear visual of the road behind you before you can make any move on the thoroughfare. Scrapes and fissures on the mirror lens prevent you from doing that. Although it's only normal for vehicle mirrors to have these flaws, you need to make sure that they don't affect the way you drive. A light abrasion on the mirror lens can be remedied by applying toothpaste to the affected area. However, if the blemish is too obvious, you'll need to replace the mirror lens. That should prevent obscuring your view of the road and help you steer your way to the streets more efficiently.
Heated mirror not working
Driving in cold climates can be unforgiving to your vehicle. Frost buildup on your car mirrors can obstruct your vision and make driving hazardous. Heated mirrors can stop working properly when the wires behind the mirrors are faulty. You can replace the bad wires to restore the heating capacity of your car mirrors.
