How Your Car's Heating System Works:

Your car's Heating System warms up the cabin be taking heat from the Engine and using it to warm the air that blows through the vents. let's break it down further!


  • Coolant Flow: As your Engine runs, Coolant flows through it, absorbing heat.
  • Heater Core: The hot Coolant then flows through a small radiator called the Heater Core. This component warms the air, which is then pushed through the vents into the cabin.
  • Blower Motor: A fan blows air over the heated core and into the car, providing that comforting warmth!


The Importance of your Defrost System:

Your car's Defrost System is critical for visibility and safety! The Defrost function directs warm, dry air toward your windshield to clear away fog, condensation, and frost. This is especially important in colder weather when fogging can happen quickly as warm, moist air inside your car meets cold glass surfaces.

Your Defrost System uses both the Heater and Air Conditioning System. Here's how it works:

  • Air Conditioning Activation: When you active the Defrost, your car's A/C may kick in to help remove moisture from the air. This prevents condensation and clears the windshield faster.
  • Warm Air Flow: After drying the air, the heater warms it before it's directed onto the windshield. This warm, dry air then helps eliminate fog or frost quickly!


Key Maintenance Tips To Get Ahead Before Winter

  1. Check the Coolant Level and Quality
  2. Since the Heating System relies on Engine Coolant, it's essential to check your Coolant levels and top off if needed. Additionally, Coolant should be flushed periodically to remove contaminants that can affect performance.
  3. Inspect the Heater Core and Hoses
  4. Leaks, clogs, or corrosion in the Heater Core or Hoses can reduce the effectiveness of your car's Heating System. If you notice a sweet smell inside the car or find wet spots on the floor, you might have a Heater Core leak.
  5. Test the Blower Motor and Fan
  6. A faulty Blower Motor can lead to inadequate airflow, affecting both the Heating and Defrost functions. If the fan sounds weak or isn't working on certain settings, it might be time to replace it.
  7. Replace Your Cabin Air Filter
  8. One of the most overlooked items of Maintenance! A clogged Cabin Air Filter can restrict airflow, reducing your heater's and defrost system's efficiency. Replacing the Filter before winter can make a noticeable difference in air quality and flow.
  9. Make Sure Your AC System is Functioning
  10. Although it might seem odd, your AC is essential for defrosting, Make sure it's working properly as the AC helps remove moisture from the air before it's heated!
  11. Schedule a Professional Inspection
  12. Sometimes, heating and defrost issues aren't easy to spot. A quick inspection with us can catch any underlying issues early, saving you from a chilly ride or a fogged-up windshield on a winter morning.
