Blower Motor: Description and Operation
Rear Blower Motor
CIRCUIT OPERATION
Power for the rear blower motor is supplied on circuit C40. This circuit is protected by a 20 amp fuse located in cavity 11 of the junction block. At
LOW and MEDIUM speeds, ground for the rear blower motor passes through the temperature sensor and one or more resistors, depending on
speed selection.
Two switches operate the rear blower motor by supplying ground; the front control switch and the rear control switch. The front control switch
must be in the ON position for the rear control switch to operate the rear blower motor.
