Control Components - Manual Climate Control: Notes
The manual climate control system heats or cools the vehicle interior depending on the function selector switch (19B888) position and the temperature selected. The function selector switch position determines heating or cooling and air distribution. The temperature blend control setting determines air temperature.
The manual climate control system components are used to select:
- air inlet source (outside or recirculated)
- blower motor speed
- discharge air temperature (temperature blend)
- discharge air location (defrost, panel, floor)
- A/C compressor clutch (19703) operation
