Temperature Control

Temperature control is accomplished by engaging or not disengaging the A/C compressor and by directing system air either through or around the heater core.

In the dual zone system the air mix door is split in half and each half has its own actuator.

When the system is operating in dual zone mode, the heater and A/C programmer operates each actuator separately. Driver side discharge temperature depends on:

^ The coolant temperature.
^ The ambient air temperature.
^ The inside air temperature.
^ The LH sun load sensor.
^ The heater and A/C control SET temperature.

Passenger side discharge air temperature depends on:

^ The coolant temperature.
^ The ambient air temperature.
^ The inside air temperature.
^ The right sun load sensor.
^ The passenger climate control setting.

When the system is operating in any mode but dual zone mode, the actuators are operating in unison as the system works to maintain the heater and A/C control SET temperature.
