Why Isn’t My Car Heater Working?

December 5, 2018 5:49 am Published by Leave your thoughts

You get in your car on a cold day and turn on the heater at full blast. Then you wait a few minutes and… nothing but cold air keeps blowing out, or no air blows out at all.

Obviously, this is an uncomfortable and irritating position to be in. You expect that your car’s heater will be working and wonder what the problem could be. Luckily, automotive heating systems aren’t as complex as other parts of the car, and the fix is usually relatively simple.

That’s why it’s good to have a trusted expert in auto repair in Chino, CA on call. Gabriel’s Automotive & Towing will have your car running in top shape again in no time. Here are the possible reasons why your car’s heater has chosen to quit on you—and what to do about it:

  • Check the coolant levels: It’s possible that your car needs an antifreeze refreshment, as hot antifreeze circulates through the heater core for the system to work. If the car is blowing cold air, it’s possible this is the case.
  • Blockages: This also falls into the category of “heater blowing cold air.” There may be debris or gunk clogging the pathways so that antifreeze can’t make its way into the heater core. It’s possible a switch or valve may need to be switched to allow the antifreeze to pass through as well.
  • Bad blower motor: If the vents aren’t blowing any air at all, then you may have an entirely different problem on your hands. For example, it’s possible the blower motor has broken down. It may also be a lack of power supply to the blower motor. In this case, a blown plug, fuse or switch may be at the root of the problem. These will need to be replaced for the heater to work again.
  • Heater box: To diagnose the problem, it may be necessary to open the heater box or take out part of the dash to access the blower. This is the kind of work that’s typically best left to professional mechanics.
