Where is the rearview mirror heating switch for Cadillac XT4?
1 Answers
Cadillac XT4's rearview mirror heating function does not have a separate switch. Once you turn on the rear window defrost button, the glass heating will simultaneously activate the rearview mirror heating. Therefore, these two functions are linked, and there's no need to operate the rearview mirror heating separately. Below is relevant information about rearview mirror heating: 1. Introduction: The rearview mirror heating function refers to heating the mirror surface through electric heating wires embedded behind the lens when driving in rainy, snowy, or foggy weather, ensuring clear visibility. Like the headlight washer, the exterior rearview mirror heating is an interconnected function that is easily overlooked. In fact, it's very simple—if your vehicle has rearview mirror heating, just press the rear window defogging button directly (some vehicles may have a separate heating button). 2. Principle: The working principle of electric mirror heating is actually very simple and cost-effective. By installing heating elements (electric heating films) on both side rearview mirrors, when the rearview mirror heating function is activated during rain or snow, these heating elements can quickly reach a certain temperature (usually between 35-60 degrees Celsius) within minutes, achieving anti-fog and deicing effects.
