Why does the car fan not run in cold weather?

The vehicle engineers already know this secret and have programmed it into the car.

This knowledge is helpful to all drivers, even if you never plan to drive in cold weather.

Why does my car heat up so fast?

It traps the heat in, just like closing the oven door. If your car has an automatic climate control system that allows you to dial in the temperature then there is no need to worry about these suggestions to make them heat the car faster, most of these cars do it automatically.
