Q: How does the rear window defroster work?

asked by on December 15, 2015

How does the rear window defroster work?

Your car is equipped with both a front and rear defroster. While the front defrost is tied into your air conditioning system and uses the fan, the rear defrost is different. Here’s what you need to know to work it:

  1. Turn the engine on.
  2. Push the Rear Defrost button.
  3. The system will defrost the rear glass and then turn off after a set period of time.

Tips

  • You can turn the rear defrost off yourself by pushing the button again.

  • The rear defrost will only work if the engine is running.

  • The rear defrost will turn off if you cut off the engine, or if the system detects low voltage in the battery.
