Blower Motor: Description and Operation
The blower motor and blower wheel are located in the passenger side end of the HVAC housing, below the glove box. The blower motor controls the
velocity of air flowing through the HVAC housing by spinning a squirrel cage-type blower wheel within the housing at the selected speed. The blower
motor and wheel can be removed from the housing inside the vehicle without removing the dash or HVAC housing assembly
The blower motor will only operate when the ignition switch is in the ON position, and the A/C Heater mode control switch knob is in any position,
except OFF. The blower motor receives a fused battery feed through the blower motor relay whenever the ignition switch is in the ON position. The
blower motor battery feed circuit is protected by a fuse in the Power Distribution Center (PDC). Blower motor speed is controlled by regulating the
ground path through the A/C Heater control blower motor switch and the blower motor resistor.
The blower motor and blower motor wheel cannot be repaired and, if faulty or damaged, they must be replaced. The blower motor and blower wheel are
serviced only as a unit.
