What does the thermostat do to a car heater?
To help engines warm up fast and then keep it at a steady temperature, manufacturers use a thermostat to control the flow of coolant. If the engine is cold, the thermostat will restrict the flow of coolant into the engine, allowing it to warm up quickly.
Why does my car heater not turn on?
Your car’s heat uses a blower fan to blow air over the heater core and then into the cabin of your car. Over time the blower motor can short out or stop working entirely which means it won’t be spinning the fan to blow air over the heater core.

Why do I not get heat from my car heater?
That’s why you won’t get heat until the car has been running for a couple of minutes. As the engine gets hotter, so does the coolant. Because we rely on the coolant system to provide us with heat through our heaters, there are now a few components that can fail and mean that you’ll never get heat out of your car heaters.

What to do if your car heater is stuck?
Thermostat – A faulty thermostat can cause too much or to little cooling. If it’s stuck open, the engine is going to take longer to warm up because coolant will circulate all the time. You can remove the thermostat and test it in a pan of almost boiling water, it should open just before it reaches the boiling point, then close as the water cools.
