Where is the rearview mirror heating switch on the Buick Verano?

The rearview mirror heating switch on the Buick Verano is located directly above the air conditioning fan speed knob. This switch is labeled "rear." Turning it on activates the heating function for both the upper and lower rearview mirrors as well as the rear window. A yellow light indicates that the heating is on, while the light turning off means the heating is deactivated. The heating function will automatically turn off after a period of use. Rearview mirror heating is particularly useful during rainy or snowy weather. When activated, the heater behind the mirror quickly warms the surface, gradually removing rain or fog, eliminating the need for the driver to frequently wipe the mirrors manually, thereby reducing driving hazards. How to use the rearview mirror heating function: There are generally two ways to activate the rearview mirror heating function. One is combined with the electric rearview mirror adjustment knob—simply rotate the knob to turn it on. The other is located on the air conditioning control panel—pressing the heating button activates the function. No manual angle adjustment is required, as the driver's side has a dedicated adjustment button. Principle of the rearview mirror heating function: After pressing the button, the electric heater behind the rearview mirror glass rapidly heats up to a fixed temperature within minutes, typically between 35-60 degrees Celsius. The heat is distributed across the left and right rearview mirrors. As the temperature rises and evaporation occurs, water droplets on the mirror surface gradually shrink, and fog slowly dissipates, effectively defrosting and defogging the mirror. However, if the rain is particularly heavy, the effect may diminish and become less noticeable. Precautions for using the rearview mirror heating function: The principle of rearview mirror heating involves electric heating wires embedded in the mirror. These wires consume a significant amount of power. When using this function, ensure the car is running. Avoid activating rearview mirror heating while the vehicle is stationary to prevent draining the car battery, which could lead to insufficient power for starting the engine. Other methods for defogging rearview mirrors include: Opening windows slightly to create air convection between the inside and outside of the car, reducing the temperature difference and gradually eliminating fog. Adjusting the car's air conditioning to the appropriate setting to blow warm air for defogging.

I've been driving the Verano for almost three years now, and this rearview mirror heating switch is truly a rainy-day lifesaver. It's located in the area of the air conditioning control panel - look carefully for the button with a square containing a wavy line icon. Pressing it simultaneously activates both the mirror and rear windshield heating. Important reminder: make sure to use it only after the car is started, otherwise the battery can't handle it. The heating effect usually becomes noticeable in about 3-5 minutes. During heavy rain, I always turn this feature on - water droplets on the mirrors evaporate quickly, making lane changes much safer with clear rear visibility. If pressing it doesn't work, there's an 80% chance it's either a blown fuse or damaged heating wires inside the mirror, requiring a shop visit. Don't leave this function on continuously - it automatically turns off after about 15 minutes, which is a really thoughtful design.

I just picked up my Verano last week, and the salesperson specifically introduced this feature to me. The rearview mirror heating switch is located in the air conditioning control area on the center console, marked with a rectangle and three wavy lines. When pressed, an indicator light on the dashboard will illuminate, indicating it's working. It's especially useful on rainy days, keeping the rearview mirrors clean and significantly improving visibility. Note that it's best not to use it in dry weather, as the high heating temperature can damage the mirror. I tested it, and it automatically turns off after about 10 minutes, which is a thoughtful overheating prevention design. Also, don't confuse it with the rear window defogger—though it's the same button, the rearview mirror heating has lower power. If the button doesn't respond, it's likely a wiring issue or a blown fuse.

Having repaired Buick vehicles for seven or eight years, I'm most familiar with the Verano model. The rearview mirror heating switch is located in the middle of the air conditioning panel - it's the square button with wavy lines, sharing the same switch with the rear window defroster. It only works when the engine is running, consuming about 200 watts of power. It automatically shuts off after ten minutes to protect the circuitry, which is a well-designed feature. If it malfunctions, first check fuse #7 (15A) in compartment D of the fuse box - just replace it if blown. For internal heating element shorts in the mirror, door panel removal is required for repair, taking about half an hour labor. Don't confuse it with the power-folding button (the round one). For rainy days, I recommend turning on the AC first before activating the heater for faster results.

Last time I drove on the highway in the rain, I found the rearview mirrors completely blurred. Luckily, the Verano has this heating feature. The switch is located at the top left of the air conditioning control panel, marked with a square and wavy line symbol. I usually press it as soon as I get in the car, and the water removal effect is remarkable—the mirrors start heating up in seconds, and the water droplets gradually shrink and disappear. A special reminder: during the rainy season, remember to check if this function is working properly. Don’t confuse it with the seat heater, whose button has a wavy line plus a human figure. If it malfunctions, it might be due to a blown fuse in the box below the left side of the steering wheel. The best part is that it automatically turns off—I tested it, and it shuts off after a maximum of 15 minutes. Driving safety is paramount, so learning to use this switch is crucial.
