Why is My Heater Blowing Cold Air?
It can get cold in the beautiful Appalachian mountains, especially if you’re car’s heater isn’t working. What do you do if the heater fan isn’t working but is just blowing out cold air? There are a few items that you can check that will give you some clues as to what is going on with your vehicle’s broken heater.
Check Your Water Level
Your car, truck or SUV uses both antifreeze and water (have you noticed that it comes premixed in the bottle from the store?) to help cool down your engine. The antifreeze does to water what the make implies – it makes it so it doesn’t freeze. If the water in your engine froze, that would be very, very bad. The antifreeze also makes it so the water doesn’t corrode your engine.
Corrosion in the engine is not good for your vehicle either. That is why we always want to be sure that we have enough coolant. Because the heater uses heat from the running engine to warm you up, you’ll only feel cold air if you don’t have enough liquid coolant.
Check Your Thermostat
Your thermostat keeps track of how hot or cold your car is. The heater uses this to control the heat of the water in your vehicle. You can see this working by starting your car and letting it run. You need to let it warm up for at least 10 minutes or so. Check and see if the gauges change. If the water temperature gauge remains cold, you’ll need to have it replaced.
Check For Clogs or Blockage
If you have water/coolant and your car’s thermostat isn’t working, you may have a blockage or clog in the line. This is a bit more technical to check, so at this point, you may want to look at getting some auto heating repair. If you feel skilled enough, you can try to clear the clog or blockage but we recommend letting a professional take care of this for you. To test the port or bleed screw turn on the engine, wait for the fan to start then open the port or screw until you hear a hissing sound.
Check The Dials
Your heating control dials could be turning on your end, but not actually turning the correct parts to make the heater work. You can check to see if they are stuck by removing the dial to see the position, turning it, and then removing again. Once you discover the problem, you’ll be ready to attempt to fix it yourself or to look for some professional auto heating repair.
