General Information

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 assembly, to any setting. The temperature control can change the vehicles air temperature regardless of the HVAC mode setting, heater or A/C.

The temperature control knob is located in the center of the HVAC control assembly. A temperature control cable mechanically links the knob to the temperature door.
