But before we get down straight to why, how and when car heating system decides to stop working, let’s have a brief understanding of the working of the car heating system.
How does a car heater in a vehicle work?
Every single automobile on road today is equipped with a heating system which is engineered to make use of heat from the engine which is converted into heated air which is then blown into the car cabinet. Few! Once the engine has properly warmed up after running for a considerable amount of time, the heated coolant is then transferred into the heater core which is located inside the passenger compartment. A heater core is a heat exchanger similar to a radiator. The heater and the air conditioner evaporator core; both are boxed in the same unit called a heater box or plenum. A plenum is responsible for diverting air to various vents through several air deflection doors and ducts. The blower motor extracts heat from the heater core and, segregating heat from the coolant flowing through it. The antifreeze then carries on to the water pump. A fan (the same one used by the air conditioner) blows air through the heater core, with the heated air then blow out through the car’s vents and warm up the interior.
Why Won’t My Car Warm Up?
Since the car heater has a direct connection with the engine coolant system, to get to the bottom of the problem, it is important to take note of few things. If you find that the thermostat isn’t moving much from the lowest reading, or the car isn’t cooperating or running properly for more than a few minutes on a cold, chilly day, then know that your car heating system is rolling out signs of failure. Here are few things to look for to determine the root cause of the problem and must be treated accordingly. If the repair is simple and can be done at home, then do it right away, if not, then don’t waste in getting your car to the professional mechanic.
Low Coolant Level: Yes, according to the “popular” mechanic Jose Guzman, you first need to check that the car’s various fluid levels are reaching their optimum level. Be cautious when you check your car for fluid levels, turn off the engine and let the engine cool down. While the engine is cold check the radiator fluid level. Insufficient coolant in the coolant reservoir could be the reason why there is not enough heat being transferred inside the passenger compartment.

Blown Fuse: Another prominent reason why your car heating system isn’t working properly can be malfunctioning of the electrical system associated with it. A blown fuse which is associated with the control valve can be the reason why the heater isn’t working properly, with a blown fuse of the control valve you’ll notice that the heater is blowing cold air instead of hot. Taking the help of the vehicle owner’s manual get down to the task of locating the control valve fuse mechanism and inspect if it is working just fine. In case you notice a problem, don’t waste another second in getting it replaced.
Faulty Thermostat Valve: Sometimes it is not the heater but the thermostat valve that isn’t working to the best of its capability. For this, you need to inspect the thermostat valve. Start your car and let it run. Meanwhile turn on the car heater. While the engine is warming up, pay close attention to the hot and cold indicators on the dashboard. See if they are changing temperature. If it is taking too long for the indicator to reach the point where the car is warmed up and can now be driven, then there is a problem with a stuck closed/open thermostat valve. This can also be the reason that the cabin isn’t warming up faster.

Control Valve Failure: The heater control valve is a cooling and HVAC system component that allows coolant to flow from the engine to the car heater core, which is located inside the passenger compartment of a vehicle. When the valve is opened, it allows warm engine coolant to pass and into the heater core, so that the hot air can be circulated through the vehicle’s vents. If the control valve is not working properly or is stuck, it will not allow hot air to pass into the heater core, thus the car will not warm up.
Blower Fan Failure: First locate the blower fan inside the dashboard. In almost every car model a blower fan is located underneath most glove compartments. This small fan circulates the warm air in the cabin area. If you don’t see air coming through the air ducts, then it is possible that the fan is not working fine. Referring to the vehicle owner’s manual, locate the position of the fuse box and get to the fan fuse. If the fan fuse is working just fine, then the faulty fan is the reason why your vehicle is not warming up.
