Why is my car not blowing hot air on heat?

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 do you know if your heat is on?

Once you feel hot air coming through your vents, walk outside and see if the outdoor unit is running. You see, a heat pump is an air conditioner that can also provide heat during the winter. So if the outside unit is running and producing heat, then you have a heat pump.

Why does my MDX not have enough coolant?

While not having enough coolant may make your engine run hotter, it can also cause your MDX to not be able to create enough heat. Is there isn’t enough line pressure, due to low coolant, then the heater core will not be able to get any coolant itself.
