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 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.
