Why is my car not blowing out hot air?
Faulty Heater Core The heater core looks (and works) similar to your car’s radiator — it’s made up of a series of narrow tubes and fins. Faulty heater cores and low or contaminated coolant levels often come hand in hand, and both issues may lead to your engine overheating and your heater not blowing hot air.
How can you tell if your heater core is clogged?
There are several telltale signs that you’re experiencing a heater core problem:
- You have little or no heat inside your car.
- You smell coolant inside your vehicle.
- Your windows fog up.
- You see signs of a coolant leak under the dashboard.
- Your coolant level is dropping, or your engine is running hot.
What temperature should the hot air be coming out of the vent?
14 to 20 degrees
The air coming out should be 14 to 20 degrees cooler than the air flowing in. Move the thermometer to a vent in each room or area of your home. If any of the vents are much colder or warmer than another, there may be a problem with the ductwork, or the distance may be too great from the blower.
