Operation - Rear
OPERATION
The rear blower motor is used to control the velocity of air moving through the rear heater-A/C housing by spinning the blower wheel within the housing
at the selected speed.
The rear blower motor will only operate when the ignition switch is in RUN and the front A/C-heater control is set to either front control of rear
heating-A/C system or to the rear control of the rear heating-A/C system. The rear blower motor receives a battery feed through the rear blower motor
relay located in the power distribution center (PDC) whenever the ignition switch is in RUN See: Testing and Inspection.
The rear blower motor and blower wheel are factory balanced and cannot be adjusted or repaired and must be replaced as an assembly if inoperative or
damaged.
