Auxiliary Heater Without A/C

The auxiliary blower motor recycles air from the vehicle's interior. The vehicle operator can determine the intensity of the auxiliary heater by placing the auxiliary blower motor switch in one of the following positions: Low, Med, or High. Since there is no temperature switch, the temperature is controlled by the speed of the auxiliary blower motor. The auxiliary blower motor will only operate when the ignition is in the RUN position, and the auxiliary blower motor switch is in any position other than OFF.

Power is provided to the auxiliary blower motor from the underhood fuse block on the battery positive voltage circuit through the convenience center. The IP fuse block provides power to the control side of the auxiliary blower motor relays through the ignition 1 voltage circuit and convenience center.
