How The Part Works
The mirror contains a light sensor and electrochromic glass that changes tint in response to detected glare. A small electronic module monitors ambient and rearward light levels and applies a variable voltage to the glass to darken the reflective surface when necessary. The unit is powered from the vehicle’s interior lighting/auxiliary circuit and communicates no vehicle bus signals in standard installations (unless part of a larger integrated module).
How To Replace
Basic Replacement Steps (Overview):
- Park The Vehicle On A Level Surface And Disconnect The Negative Battery Terminal As A General Safety Precaution When Working With Electrical Components.
