Electronic Climate Control Module

With the use of a microcontroller, the Electronic Automatic Temperature Control (EATC) module analyzes input from the following major sources:
^ temperature, function and blower selection (made by the vehicle occupants)
^ in-vehicle temperature
^ ambient temperature
^ sunload
^ vehicle speed
^ engine coolant temperature

Using these inputs, the microcontroller determines the correct conditions for the following outputs:
^ A/C compressor clutch engagement
^ blower speed
^ air temperature blend door position
^ panel/floor door position
^ panel/defrost door position
^ air inlet duct door position
^ outside temperature display
