Why Isn't My Car Heater Working?

You get into your vehicle on a cold day with foggy windshields only to find that your heater and defroster aren't working. Whether your heater is blowing cold air or not blowing air at all, something isn't right with a component in the heating system. When it comes to the defroster, a faulty one can cause visibility issues so it is important to have a heater problem addressed and repaired quickly. 

What are some reasons why your car heater won't work?

  • The blower motor isn't working
  • The heater core is blocked
  • Low coolant level
  • Missing or defective thermostat
  • Heater core leak
  • Weak water pump

The reasons above are just some of the common causes of a heating system problem. Usually, the issue will be with the heater core which can be replaced. Other times, there are other contributing factors that can affect the temperature of the air that blows out of the vents when the heat is turned on. 

Regardless of what the cause of the problem is, you can trust that the experts here at Carlife Professional Auto Service can get to the bottom of the issue. We will work quickly to diagnose the issue and get you back on the road with working heater in no time.
