Reasons Why Your Car Heater Does Not Work Properly
There are lots of reasons why your car heater does not work correctly. It’s mainly due to the heater being used only in the winter. Hiring a service to maintain its good condition is essential each winter. In addition to that, the dials, knobs, and haptic touch screens may not have triggered the heater. Damaged dials, short circuits, and faulty touchscreens can stop a heater from operating.
#1. Faulty thermostat
The thermostat is a valve that opens and closes in order to control the coolant’s movement to a radiator and motor. It is necessary to have a working thermostat that best maintains the engine, and it operates at a suitable temperature; this is also despite the simplicity that it does have. The thermostat is broken and trapped inside the open state.
#2. Malfunctioning heater core
The car heater consists of several vents and small tubes that the radiator in a vehicle. The radiator then loses heat in the ambient air. The fan then blows heat and continues to the rear seat. Leakage and clogging in the labyrinth system of the heater core of capillaries reduce circulation and coolant levels in the vehicle’s cooling system. Polluted or insufficient coolant conditions and defective heating cores cause overheating to the motor. The result is the heater stops pumping warm air.
#3. Toxic coolant
The motor coolant consists of water and freezes, keeping the motor against excessive cooling or heat. The coolant in a car does not need to freeze in the cold or grow excessively hot in the summer; when an appropriate mixture of water and coolant is guaranteed, the air conditioning system adequately disperses and collects heat in the motor. When you turn the heat on the car during the winter season, this surplus heat pushes into the vehicle’s interior. It then warms up and clears the windscreens. The pollution in the vehicle’s conditioning system is one cause why your car heater is not working. It causes the coolant to freeze over time quickly. It generates the motor heat that stops the heater from functioning.
#4. Damaged blower fan
The heater core gathers the heat in the system and pushes it inside the cabin in hot air when heating it in the vehicle. The blower fan blows the hot air in a heat exchanger through the ventilation of an automobile. If the blower blade does not operate properly, only a slight flow originates through the vents. The harm created in the internal parts of the blow fan or the blown circuits is two causes of failure in the blower fan. If you cannot feel or hear the wind with the car heater on, the problems with a blowing fan could be the cause.
#5. Water leakage
Water leakage is a common issue with a car heater. It likewise appears in most areas, so examine the thermostat, pump, and cables for problems. The heater in a car will not work correctly if these three will leak. A heating system is functional if the winter is made more pleasurable. If you notice any of these issues or no warmth that flows from the vent, inspect the heating system by a dependable car repair company. It’s essential to resolve the heating issues right away as it is feasible. If we only ignore the case, it might result in a more expensive and significant problem in the coming years.
#6. Problematic HVAC Controls
Why my car heater is not working is not because of the knobs, buttons, and haptic feedback touch screens that trigger the heating system. But the bad touchscreens, broken dials, and shorts can result in malfunctions preventing the device from working.
#7. Blown fuses or faulty wiring
A fuse that blows may break your car’s wiring or have such a short in it as this is the same as the damaged HVAC controls, as this means the heater is not triggered as the driver controls it to function. It’s best to also know how to make your car heater hotter.
