DESCRIPTION
The Electronic Climate Control (ECC) system is an automatic A/C-heater system that monitors in-vehicle temperature through 2 sensors located in passenger compartment. One (solar) sensor is located on top of dashboard and senses sunlight. The second sensor is located in courtesy light fixture, and senses temperature in center of vehicle. A/C compressor will not engage unless temperature is above 41°F (5°C).
In addition to basic A/C-heater system components, system includes air intake temperature sensor, water (coolant) temperature sensor, servomotor and vacuum actuators. see scheme 4
System is engaged when A/C button on control panel is pressed. (Scheme 1) Pressure switch on accumulator cycles compressor clutch on and off. Airflow modes are selected by center knob on control panel. Doors are controlled by vacuum motors on left side of heater case.
