The rearview mirror heating switch on the Envision is located in the air conditioning control area of the center console, above the air conditioning cooling switch. The function of the rearview mirror heating is to heat the mirror surface, which helps to remove fog and frost, keeping the rearview mirror clear and ensuring driving safety. Taking the 2021 Envision as an example, it is a midsize SUV with body dimensions of: length 4694mm, width 1839mm, height 1686mm, wheelbase of 2750mm, and a curb weight of 1610kg. The 2021 Envision features a front MacPherson strut independent suspension and a rear multi-link independent suspension. It is equipped with a 1.5T turbocharged engine producing a maximum horsepower of 169PS, maximum torque of 250Nm, and maximum power of 124kW, paired with a 7-speed dual-clutch transmission.

I've been driving for almost ten years, and the rearview mirror heating switch on the Buick Envision is quite easy to find. It's located on the air conditioning control panel, usually sharing the same button with the rear window defroster. The button features a square with wavy lines symbol and is positioned on the center console to the right of the driver's seat. Pressing it activates the heating function, helping to clear fog or rain from the mirror surface in wet conditions for improved safety. The operation is straightforward and quick—once turned on, it typically shuts off automatically after about ten minutes to save power, which is quite user-friendly. If visibility through the rearview mirror is poor on rainy or foggy days, it's best to press it early as a preventive measure. Details may vary slightly across different model years, but the basic layout remains similar. If you can't locate it, check the owner's manual for illustrated guidance. It's advisable not to wipe the mirror manually to avoid scratches—just rely on this switch to handle it.

As a frequent business traveler, road safety is my top concern. The Buick Envision's heated mirror switch is thoughtfully designed, integrated into the air control panel with a rear defroster icon. Simply press to activate when the indicator lights up, quickly clearing mirrors in cold or foggy conditions. Its auto-timed shutoff during long drives prevents battery drain—a considerate touch. Positioned within easy reach below the steering wheel, it allows operation without distraction. While keeping wipes as backup helps, the heating function delivers thorough efficiency. Note: Switch placement may vary slightly (e.g., higher trims), but most cluster near the center of climate controls.

I really enjoy tinkering with cars, and the Buick Envision's rearview mirror heating switch isn't hard to find. It's the button with the square wave icon on the air conditioning panel—press it to clear dew or rain from the mirrors. The switch is usually tied to the rear defrost function and is compactly designed on the driver's side for easy access. It takes effect in about a few minutes and is quite practical. Just remember not to hold it down too long, as the system automatically shuts off to protect the battery. The location is consistent across most versions, but if unsure, check the manual's diagram to avoid misuse.
