Blower Motor Replacement
What is a heater blower motor?
The blower motor is a fan located in the heating ventilation and air conditioning (HVAC) ducts, usually behind the glove box. When the heater or air conditioner is active, the blower motor pushes air through the vents.
How does the heater blower motor work?
When you turn on the heater, the blower motor blows it across the hot heater core, sending heat through the vents. Likewise, when the air conditioner is active, the blower motor blows air across the cold evaporator, which blows cold air through the vents.
Heater blower motors can be damaged by fluid leaking from a heater core or evaporator. Any fluid leaks near the heater blower need to be resolved or the new heater blower will be ruined.
