#1. Malfunctioning of the heater switching system

We must first ensure that the heater is switched on before proceeding with the repair,  but first, keep in your m mind that there isn’t a single blown fuse in the entire box. The heating indication light (which is usually located on the button of the car heater) is turning on. Whenever you switch on the heating, you should hear a slight popping noise from the dashboard. If the vehicle has an automated thermal management system, check to verify that the temperature dial is cranked up. Start making sure the air conditioner is turned off. They just negate one another out when both are switched together at the exact moment. However, if your heater is on but no hot air is coming out, try the following steps below. 


#2. Blocked air filter

The car’s heating systems and air conditioning, such as your residing space, have an exhaust system or air filter. This air filter is used to supply users with clean air while preventing clogging of the heaters or air conditioner heat exchanger. If such a filter becomes clogged due to neglect, the vehicle heater and air conditioner will stop operating. This, on the other hand, is the simplest to cure and will take no and over 10 to 15 minutes.

In your automobile, look for the cabin air filter. It’s generally hidden underneath the glove compartment.  The precise position may be found in the owner’s handbook or even on google.  Remove the filter and inspect it for damage. Check the condition of the filter by removing it. You should change it if there is debris and twigs within. Replace the filter with one obtained from a nearby parts store.


#3. Faulty thermostat

The thermostat valve isn’t working properly; if the car’s cabin air filter is in fine condition, the heater still won’t turn on and not produce hot air, the thermostat valve should be checked next. Below is how: Use the e-brake and park the vehicle on a horizontal surface. Check to see whether the car is warm. Allow the engine to cool completely if you’ve just returned from a ride or if it’s been working. Raise the hood and find the radiator when the automobile engine is cold. A large pipe leading to the engine is located on the upper edge of the heater. Keep in mind the automobile is cooled. Inspect the thermostat valve. The valve is faulty if the spring is unfastened and can be readily squeezed. 

Repair the valve to one with the same Thermal rate as the original. If you’ve spilled any coolant, top it up using distilled water. These tips will fix the majority of car heating difficulties. Though your car heater continues to pump cold air then after, even though the thermostat is already in proper working order, you may have a problem with a malfunctioning heater core.

The heat exchanger that warms the air in the cabin is known as the heater core. The coolant’s salt and rust might clog the thin tubes inside.

Since this issue necessitates dismantling the entire automobile inside, it is best left to the specialists.
