Reasons Why Your Heater Isn’t Working

Is your car heater having trouble?

The weather may be getting colder, but at least when you go for a drive, your car is nice and toasty warm, right?

Well, maybe not, if your heater has been having trouble.

If you've noticed that your car isn't heating up as it should – or if your vents aren't outputting heat at all – you could have a serious problem that needs to be addressed. There are a number of reasons why your car's heater may not be working. Here are some things to look for when inspecting your vehicle:

  • Broken Fans: The fans that circulate warm air throughout your car are generally located under the glove compartment. If yours aren't spinning, this will impact your heating system's ability to work. Check the car's fuse box to see if there is a problem with the fan fuse or the spinning mechanism itself.
  • Improper Fluid Levels: You need a certain amount of radiator fluid to ensure that heat from the engine can transfer into the car. Periodically check your levels – but make sure you do it when the engine hasn't been run in a while.
  • Faulty Thermostat: Your heat might not be working because your car might not realize what the temperature is. Specifically, the thermostat is designed to be closed when you first start your car, forcing the coolant to reach a certain temperature. At this point, the thermostat will open, letting the coolant flow into the radiator. This heats your car and cools your engine, but if anything is wrong with the thermostat the process breaks down.
