The Heater System Wiring/Circuit system consists of battery, fusible link, ignition relay, fuse box, blower  motor, fan switch, and ignition switch.

The heater controls, consisting of two levers and one knob, are located in the middle portion of the instrument panel. There are the AIR lever which selects the air outlet, the TEMP lever which controls the temperature and the FAN switch knob which regulates air flow with the fan. Heater ducts for rear seat occupants are standard equipment on European and Australian models.

The outside air drawn in through the cowl top grille is directed through the air intake box to the heater unit by the fan. The heater unit includes an air mix door which controls the air temperature, and a ventilation of air flow. The intake door inside the intake box shuts out the outside air when the heater  is off.
