DESCRIPTION AND OPERATION
Control Components
Manual A/C
The climate control system heats or cools the vehicle interior depending on the function selector
position and the temperature selected. Function selector position determines heating or cooling and air
distribution. The temperature blend control setting determines air temperature.
The manual climate control components are used to:
zselect air inlet source (outside or recirculated).
z select blower motor speed.
z select discharge air temperature (temperature blend).
z select discharge air location (defrost, panel, floor).
z select A/C compressor clutch operation. Component Locations SECTION 412-

For example, if you don't know the specific system in which the ignition switch is located, look up ignition
switch in the wiring diagram component location tables and go to the appropriate wiring diagram(s) which
contain either full or partial views of the ignition swit ch. The full view of the ignition switch is located in
Power Distribution.
The first listing for the component will be the full or most complete view of the component. Additional
listings will be partial views of the component. Not all components are used on all models.
All components will have a partial view in Gr ound Distribution and Power Distribution. Data Link
Connectors show connecting circuits between modules. Alternate names for components may be listed in
wiring diagram component locations tables.
