Safety Warning
DIY auto repair can cause serious injury, fire, or vehicle damage. These guides are for informational purposes only. Always follow OEM torque specs, wear PPE, and consult a certified mechanic if you are unsure. You are solely responsible for your safety.
Heated Rear Windshield And Door Mirrors
The heated rear windshield and door mirrors are activated by pressing the switch on the climate control module (CCM) (3/112). The climate control module (CCM) transmits information to the central electronic module (CEM) (4/56) about the selected heating status. The central electronic module (CEM) transmits a signal to the driver's door module (3/126) and passenger door module (PDM) (3/127) for the heated door mirrors and to the rear electronic module (REM) (4/58) for the heated rear windshield.
The central electronic module (CEM) also transmits information to the climate control module (CCM) about whether the seat heaters are activated or not. The climate control module (CCM) uses this information to light / turn off the LED on the button.
