Did you know that your vehicle’s heating system is meant to do more than keep you warm? The heater is a vital safety component designed to not only keep a vehicle’s cabin comfortable, but to also defrost the windshield. If you are having issues with your vehicle’s heater, Twin Peaks Auto Repair offers comprehensive auto heating repair services in Longmont that will keep you safe and warm all winter long.
Aside from blowing cold air, the air vents can blow fog or smoke and a sweet stench when the heating system starts to fail. Your vehicle may also see constant coolant loss when your heater is faulty. In any case, it’s important to address the problem to avoid further damages or expense.
How a Vehicle’s Heating System Works
The coolant in the vehicle is heated by the engine where it is then pushed through the heater core located behind the dashboard. A fan blows air through the heater core, which is passed through the vents in the cabin.
What Causes a Vehicle’s Heater to Stop Working?
There are several reasons why a vehicle’s heating system can stop working:
- Low coolant
- Faulty heater core
- Clogged/broken heating controls
- Thermostat malfunctions
- Water leaks
- Damaged wiring

Vehicle Heater FAQs
Why is my car heater blowing cold air?
Several faults can affect cabin heat, including coolant circulation, heater controls or airflow problems. The cause depends on the vehicle. An inspection helps distinguish these issues before parts are recommended.
Does poor defrosting need attention?
Yes. Reduced windshield clearing can affect visibility. Arrange an assessment and avoid driving when you cannot keep the windshield clear. Tell the shop whether the problem changes with fan speed or engine temperature.

The cost depends on the source of the problem, the vehicle and access to the affected components. Describe the symptoms when requesting service so the shop can discuss the appropriate diagnostic work.
