Blower Motor: Description and Operation
Circuit Operation
CIRCUIT OPERATION
With the ignition switch in the RUN position, power flows from the 25 Amp fuse, in cavity 7 of the fuse block, to the blower motor. Blower motor
speed is controlled by the fan control switch located in the instrument panel, and the resistor block.
Blower motor LOW speed operation is accomplished on the C4 circuit. When the control switch is moved to the LOW speed position, current is
passed on the C7 circuit through the blower motor resistor to the C4 circuit. It then flows through the blower motor switch to the Z8 circuit. The
Z8 circuit terminates at a grounding point on the instrument panel left center support.
The operation of the blower motor M1 and M2 speed operations is the same as the LOW speed except, the C5 circuit is used for the M1 speed and
circuit C6 is used for M2 speed operation.
Blower motor HIGH speed operation is accomplished on the C7 circuit which supplies battery voltage directly to the blower motor. There are no
resistors used in the HIGH speed mode.
