Blower Motor: Description and Operation
Blower Motor = Hardwired To Control Head = Resistor Block
The blower motor and blower wheel are located in the passenger side end of the heater-A/C housing, below the glove box. The blower motor controls the
velocity of air flowing through the heater-A/C housing by spinning a squirrel cage-type blower wheel within the housing at the selected speed. The
blower motor and blower wheel can only be serviced with the heater-A/C housing removed from the passenger compartment.
The blower motor will only operate when the ignition switch is in the ON position, and the heater-A/C 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). The blower motor relay control circuit is protected
by a fuse in the junction block. Blower motor speed is controlled by regulating the ground path through the heater-A/C mode control switch, the blower
motor switch, the blower motor resistor, and the voltage reduction relay.
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
each serviced separately.
