Why Is My Car Heater Blowing Cold Air?

The weather will only get colder in Colorado in the next couple of months, which means all drivers will be cranking their heaters on their daily commutes. If your heater starts malfunctioning and blowing cold air in the midst of winter, you probably want to get that fixed ASAP.

Your vehicle's heating and cooling system has many complex components, which means this sort of problem can arise from any parts. Because of this, it's not easy to diagnose this problem, let alone try to fix it at home. Luckily, you can count on the pros at Phil's Pro Auto Service to get your heater running in no time.

Below are some of the most popular explanations for a cool-blowing vent when the heater is on:

Insufficient Amount of Coolant

The coolant in your car's heating and cooling system has anti-freeze properties. When your car runs low or out of coolant and you continue to run your engine, it can do a number on your motor. This is why your vehicle needs to warm up before you start feeling the heater kick in. Please make sure you regularly check your coolant levels.

Issues with the Heater Core

The heater core is responsible for ensuring you get the right heating temperature. An obvious symptom of a damaged heater core is foggy windshields and windows.

Clogged Heater Controls

If you have an older vehicle, the buttons for the heater can sometimes get jammed and stop working. If your coolant levels look sufficient and your heater core checks out, you may just need to change out these button controls.

In addition to these possible problems, a faulty thermostat and leaks can also make your heater blow cold air. If your car requires heating repairs, please do not hesitate to bring it to the HVAC system experts at Phil's Pro Auto Service in Greeley, CO.
