On every vehicle with a heating system there will be a heater motor that animates the system. A heater motor is usually located behind the dashboard and is responsible for blowing air across either an evaporator or a heater core. This air is processed by a series of vents to direct the air to various positions. For example, heater, air conditioner or defrost modes. Most

heater motors

are powered by a basic electrical circuit that utilizes a multi resistor or a solid state resistor to control different fan speeds.

Heater motors

may eventually wear out and need replacing, with the most common symptom of malfunction being a lack of air regardless of what position you have the blower set at. If this is the case then replacement quality

heater motors

for every make and model of car are easy to source.
