Several components make up the heating system, we can diagnose any problem with your heater.
Checking hoses, belts and keeping the coolant clean and filled are simple basic maintenance that will help keep it working.
In general terms, a heating system works when the vehicle receives heat from the engine’s coolant system. Once the engine reaches its operating temperature — controlled by the thermostat — it heats up the coolant and water mixture, passes it through hoses and valves and into the heating core, which resembles a miniature radiator. if your car’s heater suddenly stops working in the middle of winter, it can make it downright miserable.
Not only would the inside of your car feel like an ice box, but a broken heater can prevent your defroster from blowing warm air to your windshield to eliminate ice and fog, which can pose a hazard while driving. Not having a working heater could even become a dire situation, if you end up stranded.
Common issues with automotive heating systems
A heater can stop working for a number of reasons, including:
•A low antifreeze/water level in the radiator due to a leak in the cooling system.
•A bad thermostat that isn’t allowing the engine to properly warm up.
•A blower fan that isn’t working properly.
•Coolant that contains rust particles or becomes otherwise contaminated and is blocking the heating core from circulating air into the cabin properly.
One of the most important components, the heater core, which acts like a small radiator, passes the hot air from under the dashboard into the vehicle.
