What to Do When Your Car Heater Won’t Work
Your car heating systems need to be correctly functioning especially during winter to provide you with the much-needed warmth in our cars. However, sometimes they fail. Your vehicle might start blowing cold air which might be very miserable. When a vehicle is not adequately heated, one might feel as if he or she is in a freezer. Remember that a malfunctioning heating system in your car prevents your defroster from eliminating ice and fog. As such, you are prone to many risks when driving. Your car heater might fail to work due to low water levels in the radiator. The system in your radiator might be allowing some leaks.
Additionally, a damaged thermostat might prevent your engine from warming up. There is a need to worry. You need to do the following to correct the mess.
Check the coolant
First, ensure that the car is off. Wait until the engine cools down so that the cooling system can depressurize. Look at the level of the coolant. Most likely you will note that the coolant level is low. This means that the fluid which is supposed to circulate through the heater core is not flowing. Thus, your coolant is not adequately heated up. To fix this, you need to find whether there is a leak. If there is a leak, call a mechanic to fix it. If you see that there is no leak, fill the coolant.
Check the engine
You might find that the cooling system is full and does not have leaks. Here, you need to start the engine. Give it time to warm up. As this process goes on, you need to check the temperature of the heater. This can be easily achieved using a non-contact infrared thermometer. There is a problem is you find that the hoses in the coolant systems do not have the same temperature. This indicates that the heater core is likely to be blocked. For the cars which use valves, you need to check whether these valves are functioning as required. If the valve is stuck, the coolant will not flow through the heater core. Thus, your car will not work properly.
Debris in the Heater Box
Sometimes you might realize that the hot antifreeze is circulating in the heater core, but the car is not warming. Most likely, there is debris in the heater box. This interferes with the normal functioning of the whole system. It is a severe problem which requires a mechanic.
Check the Thermostat
When you switch the thermostat and notice a movement of the blend door, then the blend door and other components which form this system might be having a problem. For the best corrective action, you need to contact your mechanic.
A car which is not warming up poses a significant risk to the driver and other occupants of the vehicle.
