Step-by-Step Guide: How to Use the Trick
-
Start your car and immediately turn on the defroster at full blast to clear the windshield.
-
Set your ventilation system to recirculate (so it uses inside air rather than cold air from outside).
-
Adjust the temperature to the highest setting.

Once the windshield is clear, switch airflow to the floor vents—this helps warm up the cabin efficiently.
-
After a few minutes, switch back to fresh air mode to prevent window fogging and maintain good air quality.
Pro Tip: Keep your coat on for the first minute or two—it’ll feel warm faster as the cabin temperature catches up!
Why This Technique Works
By recirculating the air inside your car, the system doesn’t have to heat freezing outside air. This allows your heater to work more efficiently, warming both you and the cabin faster.
It also reduces idling time, which means you’re saving fuel, producing fewer emissions, and spending less time waiting around in the cold.
Benefits of Using This Warming Technique
-
Faster heating: The cabin and windshield warm up in less time.
-
Fuel efficiency: Less idling means lower fuel consumption.
