What Are GMC Sierra Power Folding Mirrors?

GMC Sierra power folding mirrors are a great feature for any truck owner. They allow you to fold in the side mirrors when parking or entering tight spaces, making it easier to maneuver your vehicle. This also reduces the risk of damaging your mirror by hitting something while driving or parking. The power folding feature is available on many GMC Sierra models and offers convenience and safety benefits that make it a popular choice among drivers.

Power folding mirrors can be found on select GMC Sierra models from 2014 onwards, including the SLE, SLT, AT4, and Denali trims. When activated, these mirrors will automatically fold inwards when the ignition is switched off or when reverse gear is engaged. This makes it easy to park in tight spots without worrying about hitting something with your mirror. Additionally, these mirrors can be manually folded in at any time using a button located on the door panel near the window switches.

The power folding feature adds another layer of convenience to an already versatile vehicle such as the GMC Sierra pickup truck. It allows drivers to easily navigate tight spaces without having to worry about damaging their mirror due to poor visibility or misjudged distances while reversing into a spot. Power folding mirrors also increase visibility while driving by reducing wind noise and drag caused by extended side view mirrors which may otherwise impair your view of other vehicles around you on the road.

Common Reasons Why GMC Sierra Power Folding Mirrors May Not Work

If you own a GMC Sierra with power folding mirrors, chances are that at some point you’ve encountered an issue with them not working properly. The most common reasons why this can happen include loose or corroded wiring, faulty fuses, damaged motors, and worn-out switches. Let’s take a look at each of these in more detail.

Loose or Corroded Wiring

One of the most common issues is loose or corroded wiring connections between the mirror switch and the motor itself. Over time, these connections can become loose due to vibration from driving or corrosion caused by exposure to moisture. To fix this problem, you’ll need to check all the wiring connections and make sure they’re secure and free from corrosion.

Faulty Fuses

Another potential cause for GMC Sierra power folding mirrors not working could be faulty fuses in the fuse box under your hood. If one of these fuses has blown out due to excessive current draw (caused by a short circuit), then it will need to be replaced before your power folding mirrors will work again.

Damaged Motors

In some cases, the motor that powers your GMC Sierra’s power folding mirrors may have become damaged due to wear and tear over time. If this is the case, then it will need to be replaced if you want your power folding mirrors back up and running again.

DIY Solutions to Fix GMC Sierra Power Folding Mirrors Not Working

If your GMC Sierra power folding mirrors are not working, you may be looking for a DIY solution to fix the issue. Fortunately, there are some relatively simple steps that you can take to get your mirrors back in working order. Here is a look at some of the most common DIY solutions to help fix GMC Sierra power folding mirrors not working:

Check Fuses and Relays

One of the first things you should do when troubleshooting any electrical component in your vehicle is check fuses and relays. If either one of these components has gone bad, it could prevent your power folding mirrors from functioning properly. To check them, simply locate the fuse box under the hood or inside the cabin and inspect each fuse and relay for signs of damage or corrosion. If necessary, replace any damaged components with new ones.

Clean Connectors

Over time, dirt and debris can build up on connectors which can cause them to become corroded or otherwise malfunctioning. This can prevent power folding mirrors from operating correctly as well. To clean connectors, use an electronic contact cleaner spray followed by a lubricant such as WD-40 to ensure they are free from dirt and grime buildup.

Replace Power Mirror Switch

The power mirror switch is responsible for activating the motor that moves your side view mirrors in and out when you press it. It’s possible that this switch has gone bad over time which is why your GMC Sierra’s power folding mirrors aren’t functioning properly anymore. To replace it yourself, simply locate the switch on its mounting bracket near the driver’s side door panel then unscrew it using a Phillips head screwdriver before replacing it with a new unit purchased from an auto parts store or online retailer like Amazon or eBay.

Professional Repair Services for GMC Sierra Power Folding Mirrors Not Working

If you own a GMC Sierra truck, you know that the power folding mirrors are one of its most convenient features. However, if these mirrors stop working properly, it can be very inconvenient and even dangerous to drive without them. Fortunately, professional repair services are available for GMC Sierra power folding mirrors not working properly.

When your power folding mirror stops working correctly, there are several possible causes that could be responsible. The first possibility is a wiring issue in the mirror itself or within the vehicle’s electrical system. If this is the case, then a professional technician will need to inspect both areas to identify and address any issues found in order to restore proper functionality of your power folding mirror.

Another potential cause of malfunctioning power folding mirrors on GMC Sierra trucks is a problem with the actuator motor or control switch. In this situation as well, an experienced technician should be able to diagnose and repair any faults found in either component so that your mirror works as intended once again.

Finally, mechanical problems such as broken parts or worn out components might also lead to a non-functioning power folding mirror on your GMC Sierra truck. A qualified technician can replace any faulty parts and lubricate moving components so that everything works together smoothly again for reliable performance over time.

Tips and Tricks for Maintaining Your GMC Sierra Power Folding Mirror’s Performance

Maintaining the performance of your GMC Sierra Power Folding Mirror is a must for ensuring its durability and longevity. Here are some tips and tricks to help you keep it in top shape:
