OPERATION

The rear blower motor is used to control the velocity of air moving through the rear HVAC housing by spinning the blower wheel within the HVAC housing at the selected speed.

The rear blower motor will only operate when the ignition switch is in ON and the rear blower motor switch located in the front accessory switch panel is ON. 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 ON 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 found inoperative or damaged.
