What to do if the heater in the car is not working: step-by-step instructions

When the heater starts malfunctioning, it's essential to address the issue promptly, especially during winter. SSPDaily has prepared some tips to help you tackle this problem.

Check the thermostat

A faulty thermostat can cause the heater to blow cold air or not work at all. You can check it by starting the car and observing the temperature gauge on the dashboard. If the gauge stays on the cold side or fluctuates erratically, it indicates a problem with the thermostat. It's best to contact a mechanic to have it checked or replaced.

Check the coolant level

Low coolant levels can cause the heater to not warm up properly. Ensure that the coolant is filled to the proper level and check for leaks in the cooling system. If any leaks are found, they should be repaired immediately.

Check the motor

A faulty fan motor can hinder the proper distribution of hot air from the heater. Thoroughly inspect it for any signs of wear or damage and ensure it's running at the correct speed. If necessary, consider repairing or replacing the fan motor to restore efficient heating to the vehicle.

Professional inspection

Certified mechanics can conduct a comprehensive diagnosis of the car's heating system and identify any underlying issues causing a lack of heat. This involves evaluating the heating system components and electrical connections to pinpoint and resolve any issues affecting the heater's performance.
