3 Causes Why Your Car’s Heater Isn’t Working

Failed Blower Motor

A failed blower motor is one of the most common issues that cause your vehicle to not have heat going through the vents, and it’s an obvious problem. If you turn on the climate control and no air comes through the vents, then you know that it’s likely the blower motor has stopped functioning.

Heater Core Is Leaking or Clogged

Coolant runs through a heater core inside the cabin to provide the warmth needed for the blower motor to push through the vents. However, if the vents are blowing air but it’s not hot, then the heater core could be leaking or even clogged, causing it not to wam up.

Malfunctioning Blend Door Actuator

Sometimes, everything works as intended, but a malfunctioning blend door actuator could be sending the hot air somewhere other than the selected setting within the climate control unit. The blend door actuator lets you adjust which vents push the air out, which can be tested by selecting different climate settings and listening for any unusual noises.

Although these are the most common issues for causing heat to stop working in a vehicle, you should visit a trusted service centre to have your vehicle inspected and repaired correctly. Sometimes multiple issues are contributing to the heat not working, so save yourself the hassle and enjoy warm drives by booking an appointment at our shop.
