Civic CX Hatchback L4-1590cc 1.6L SOHC MFI (1997)
Control Assembly: Description and Operation
The air delivery system directs the flow of air used by the heater and air conditioner systems.
Mode Selection
Mode selection is controlled by the mode switches in the heater control panel and the mode control motor. When you select a specific mode,
voltage is applied through the dimming circuit to the LED, which comes ON, indicating the mode selected. Ground is provided to the mode
control motor through that mode switch. The motor then runs until the air control door reaches the proper position.
Fresh/Recirculation Selection
When you press the fresh or recirculation button, a ground signal is sent from the heater control panel to the recirculation control motor. The
motor then runs until the recirculation door reaches the proper position. Battery voltage is also applied through the dimming circuit to the
corresponding LED, and the LED comes ON.
