Where is the rearview mirror heating switch for the Buick GL8?

The rearview mirror heating switch for the Buick GL8 is located on the right side of the center console. The icon features a square with three arrows inside. There is no separate rearview mirror heating switch; it is integrated with the rear window defroster switch. 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 frequent manual wiping and 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—press the heating button to activate it. No manual angle adjustment is needed, as there is a control button on the driver's side. 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. Heat is then emitted from both left and right rearview mirrors. Simultaneously, as the temperature rises and evaporation occurs, water droplets on the mirror surface shrink, and fog gradually dissipates, effectively defogging and deicing 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, which consume significant power. When using this function, ensure the car is running. Avoid activating rearview mirror heating while the vehicle is stationary to prevent draining the battery and potentially causing starting issues. Other methods for defogging rearview mirrors include: Opening windows slightly to allow 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.
