Heater Mode

The purpose of the heater is to supply heat to the interior of the vehicle. The vehicle operator can determine the level of heat by turning the temperature control, located on the HVAC control unit, to any setting. The temperature control can change the vehicle's air temperature regardless of the HVAC mode setting: heater or A/C.

The air temperature is controlled by moving the temperature control lever. Moving the air temperature lever mechanically moves the air temperature door. They are linked together by the air temperature cable. The air temperature door position determines the amount of air directed to flow across the heater core.
