Control Assembly Description: CJ3

Control Assembly Description (CJ3):

The knobs and the levers on the control head (7) regulate the operation of the A/C system. The A/C system temperature can also be regulated for driver and front passenger individually, by use of slide levers in the center of the control (1). The compressor clutch and the blower connect electrically to the control head by the wiring harness. The blower circuit is open in the off mode. The four blower speeds, available in the remaining modes, provide the air flow.

Cooled and dehumidified air is available in the following modes:
^ Max (10)
^ Normal (11)
^ Bi-level (12)
^ Defrost (16)

The temperature levers control the temperature valves through the potentiometers in the control and the electric motors attached to the heater module. The modes of operation are controlled by a signal to the five solenoid valves. The valves control the vacuum valve positioning actuators. The following blower speeds are controlled in all modes by a five-position blower switch in the control head (7):
^ Off (2)
^ Low (3)
^ Medium 1(4)
^ Medium 2 (5)
^ High (6)

The blower is turned off in the OFF position (2). The temperature valve position is independent of mode selection.
