Commander 4WD V8-4.7L VIN N (2006)
The rear A/C-heater control (1) is located on the right quarter interior trim panel and allows intermediate seat passengers to adjust rear air distribution,
temperature and blower motor speed when the rear on/off control switch in the accessory switch bezel is set to the On position.
The rear A/C-heater control contains:
-
a rotary control knob for fan speed selection and turning the rear heating-A/C system off (2).
-
a rotary control knob for temperature control of the rear discharged air (3).
-
a rotary control knob for mode control of the rear discharged air (4).
AUTOMATIC DUAL ZONE
The A/C-heater control (1) for the automatic temperature control (ATC) dual zone heating-A/C system allows both the driver and the front seat
passenger the ability to individually regulate air temperature for their side of the vehicle. All controls are identified by ISO graphic symbols.
The ATC A/C-heater control and integral computer is located in the instrument panel and contains:
-
a push button A/C on/off control (2). The Snowflake button contains an LED that illuminates when the A/C system is in operation.
-
a push button rear window defogger on/off control (3). The defogger button contains an LED that illuminates when the rear window defogger
system is in operation.
-
an infrared sensor (4) that detects thermal radiation emitted by the front seat occupants and their surroundings
-
a push button air recirculation control (5). The Recirculation button contains an LED that illuminates when the recirculation function is manually
activated.
-
a rotary control knob for mode control of the discharged air (6).
-
two rotary control knobs for individual driver and front seat passenger temperature control of the discharged air (7).
-
a rotary control knob for manual and automatic fan speed selection and turning the heating-A/C system off (8).
-
Auto mode provides variable air recirculation under high temperature and humidity conditions. Because recirculation is generally accompanied by
increased fan noise, the proportion of recirculated to outside air gradually approaches full recirculation over a broad temperature range.
The A/C-heater control for the ATC dual zone heating-A/C system is diagnosed using a scan tool. Prior to replacing an A/C-heater control, check for any
