Fixing a Bad Car Heater

Don't get caught freezing this winter

Don’t get caught freezing this winter

The brutal Texas summer is now behind us and the winter months have began. This is the perfect time to make sure your vehicle’s heating and A/C system is working, because if not you could suffer some very uncomfortable commutes in the months ahead.

You’ll know if your car’s heater isn’t working. Odds are you’re experiencing one of the following:

  • Vents are blowing out cold air instead of heat
  • Vents could be blowing out no air at all
  • Seeing an antifreeze leak or noticing a strong antifreeze odor inside the cabin

More than likely there will be a problem with the heater core, which acts like a mini-radiator and sits right behind the dashboard. Many drivers put off this repair for as long as possible in some cases because the project can be very difficult to the amateur mechanic and parts and labor are often expensive when it comes to heater core replacement.

The first thing you should always check for is a leak. Checking for leaks before you start detaching and disassembling parts could save you a lot of time and frustration. If no leak is visible then check to see if air is coming through the vents with the heater turned on. If no air is coming through the vents then you may have a possible airflow blockage. Inspect the hoses to make sure everything is connected and nothing is loose.

Note: Don’t forget to check the coolant even if you see no leak. The levels may be below the recommended line and could be causing the heater core to malfunction.

It’s possible a buildup of outside contaminants can get clogged in the heater core and this can cause all kinds of problems with the car heater’s performance.
