If you’re like most people, you probably don’t think much about turning on your car’s heater. But if you’re cold or uncomfortable, it’s worth taking a few minutes to learn how to do it.

Once you find the switch, turn it on by pressing down on it until the light comes on. If your car has air conditioning, be sure to set the temperature before turning on the heater.
