How do I make the air in my car warmer?
Keep the air con fans on low until you start to feel warm air, then select incoming air. Interior heat is set to full cold and fan off.

How do you check a car thermostat?
Start your car's engine and allow it to idle. Look through the radiator filler neck to see if the coolant flows. At this time, it should not be flowing as your car has not reached the operating temperature to cause the thermostat to open. If you find the coolant is flowing, it means the thermostat valve is open.
