- Why is my car heater fan not working?
If little air is coming through the vents (hot or cold), then it could be because the blower motor for the fan or a switch or resistor that controls fan speed isn't working. Another cause might be that the electronically controlled “blend doors” that direct air flow are stuck or broken.What causes a car heater fan to stop working?

- How long should my car heater take to warm up?
If you have a late-model car or SUV with a 4-cylinder engine, and it is parked outside in below-freezing temperatures, it may take up to 10-15 minutes of driving before you can get good heat from the vents. An older car with a larger engine may take 5-10 minutes of driving to warm up.There’s no real answer to how long it should take a heater to warm up during cold weather. It really depends on sev...
- How does your car’s heating system keep you warm?
The warmth from the engine goes from the radiator to the heater core, which basically acts as a heat exchanger. It allows coolant to flow through, and this flow of coolant is regulated by the heater control valve. As the engine's heat is carried by coolant into the heater core, the device starts to get warm.In a gasoline car, the heating system works by taking warmth from the engine radiator and e...

- What happens when your car’s heater core gets hot?
Driving with a faulty heater core can be risky, as it can lead to overheating and extensive engine damage. Even a clogged heater core can prevent proper coolant circulation, causing your engine to run hot.When the heater inside the car is turned on, a valve opens, allowing that heated coolant to flow to and through the heater core. There, a door opens, and the air is directed through the heated he...
