When the cold makes it’s way in we quickly notice how well our car heater is working.  Sometimes it appears to be slow to get warm. Other times it doesn’t blow as hard as we would hope or like. Sometimes it might even blow cold air!  Why??

You car heater works by blowing air from a hot engine over a heated core which then funnels it into your car through the vents.  Each of these pieces needs to be working properly for the air to perform at it’s best.  If you find it’s not performing there are a few things to check before giving us a call.

Most Common Causes of an Inoperative Heater System

Not Enough Coolant

Without enough coolant in your radiator, your car may not have a functional heating system. Be careful adding coolant to your car, it can overflow or even explode if it’s too hot when you open the radiator!

Blown Fues

Turn on your heater in your car. If you don’t hear the fan come on, one of the simplest answers is a blown fuse. Check on the fuses in your car’s fuse box and see what the heater’s fuses look like.

Water Leak

If your radiator is leaking water and coolant, that could mean there’s a crack somewhere that needs to be repaired. The mixture is an integral part of the heating and cooling system, and it can impact other important parts of your car.

Broken Thermostat

A broken thermostat will make the car think that it’s perfectly warm in the cabin when you’re freezing! Make sure that the thermostat is reading the temperature properly so that you can get toasty, warm air.

Blower Fan Isn’t Working

The hot air will struggle to come out of the system if the fan is broken in any manner. It could be a small clog or stuck fan issue, or it could require complete fan replacement.

Don’t freeze out there over something that may be a quick, easy fix! Schedule an appointment to have us check it out and we’ll let you know what’s wrong, and what needs to be done at what cost before we do anything!
