Your morning commute is already difficult and the last thing you need is for the heater to break down in the middle of winter. Not only would this make your car feel like a freezer and driving miserable, but it could keep your defroster from eliminating ice and fog buildup on your windshield. Talk about a winter driving hazard! Don’t let the lack of a working heater become a dire situation. Instead, figure out why your car heater isn’t working and get it in for auto repair in Clarkston, MI before the real winter chill sets in.
Causes of Heating Breakdowns in your Car
Here are a few reasons why you heater may stop working and what you should do to resolve the issue:
1. Low Coolant Level
Have you noticed that your car overheats when you drive it? Or that the air conditioner isn’t blowing as cold as it should? This can mean you have a coolant leak. The antifreeze is what circulates through your engine to keep everything running at a proper temperature. It absorbs unwanted heat and moves it to the radiator, where it dissipates. So if you experience problems with the heater, check your coolant level. Because coolant does not evaporate on its own, if the radiator isn’t full, you probably have a leaky hose or a broken radiator cap. To see how you should refill the cooling system, check the owner’s manual or get your car in for auto repair. This is only a temporary solution if you have a leak, but it will buy you some time to get to an auto repair center.
2. Faulty Thermostat
The thermostat controls the cooling system by opening and closing circuits as the engine warms. If the thermostat stops working, it can get stuck in the closed position. Coolant will not circulate and the heating system will not function. Replace the thermostat and you should be good to go.
3. Trouble with the Heating Core
The heating core allows coolant to pass through and puts warmed air through the heating vents. It is located on the passenger side of the car under the dashboard. But contaminated coolant can block the heating core. And a blocked heating core means no coolant flow and no heater. If this happens, you may notice coolant leaking inside your car under the dash or steam coming through the vents. Once the heating core is plugged, you need to replace it.
4. Blower Fan
Another issue might be the blower fan. If it isn’t working properly, it can’t deliver warm air to the cabin of your car. Call a professional about how to have the part repaired or replaced.
