Mode Selector

The Oldsmobile heater and A/C control has a scoffer for the following operating modes:
^ OFF
^ AUTO
^ AIR FLOW
^ VENT
^ RECIRC
^ FRONT DEFROST
^ REAR DEFOG

If the driver presses AUTO, the following actions occur:
^ The heater and A/C programmer tests the internal temperature selected by the operator and the information provided by the system's network of sensors.
^ The heater and A/C programmer then initiates the appropriate air intake point, air discharge points and activates/deactivates the A/C compressor.
