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.
Defroster Vents
Mist forms easily on the windows in cold, damp weather. The defroster vents release air towards the front and side windows. The air flow removes the mist that forms. As the air is dry, the airflow also prevents moist air from the passenger compartment reaching the glass, so countering misting. The air conditioning contributes significantly to these functions by dehumidifying the air at temperatures above 0 Β°C.
The defroster function, for the electronic climate control system (ECC), automatically sets the climate control system for the best defrosting of windshields.
