Why is my car heater blowing cold air?

Just like a house heating system, there are numerous components working together to heat your car, a variety of things can go wrong with automobile heaters. If one or more of these problems exist, your vehicle may produce cool air instead of heat.

Several factors can cause a heater to stop working, including:

  • A leak in the cooling system has resulted in a low antifreeze/water level in the radiator.
  • A faulty thermostat prevents the engine from properly warming up.
  • A broken or malfunctioning blower fan.
  • Coolant that has become contaminated with rust particles or is otherwise contaminated and is preventing the heating core from properly circulating air into the cabin.

Various forms of fixes may be required depending on the issue. There isn’t a heater unit, such as a furnace, that you can simply replace in your home. Heat is provided to the vehicle through a variety of several things. Due to the large range of possible issues, estimating a cost is quite challenging.
