Description And Operation: Operation

The rear blower motor controls the velocity of the air moving through the HVACR housing by spinning the blower wheel within the housing at the selected or programmed speed.

The rear blower motor operates only when the ignition switch is in RUN and the front A/C heater control in the Integrated Center Stack (ICS) Module is set to either front control of the HVACR system, or to the rear control, the Rear Cabin Comfort Controls (RCCC), of the HVACR system. The rear blower motor speed is controlled by the rear blower motor power module.

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.
