other sensors. This feature prevents the effects of sudden changes in air outlet temperatures due to factors such as:
Recirculating air from the engine cooling pack at low vehicle speeds Sudden changes in ambient temperature The effects of water splash
Motorised In-car Aspirator.

An intake grille (mounted on the fascia , outboard of the steering column and below the EOD vent) houses the aspirator
thermister. The remotely mounted motor / fan assembly draws ca bin air through the grille and thus over the thermistor; a
flexible hose connects both components.
The electrical resistance of the thermistor changes in response to variations in air temperatur e, this change being converted
into an electrical signal. The A/CCM uses this signal to adjust the temperature, airflow and air distribution from the air
conditioning unit.
Coolant Temperature Signal.
This signal is supplied to the A/CCM from the instrument cluster, the input being required to:
Provide blower inhibit control , to avoid the system in heat ing mode delivering cold air when the coolant temperature is below 35°C unless DEFROST is selected. To progressively increase the fan speed up to maximum blower speed during warm up control. To assist in the control of the outlet temperature. To avoid possible pump or valve damage ca used by ice particles in the coolant.
Compressor ON Signal.
This signal monitors the compressor relay to confirm the compressor operating state and so provide relevant fault
information.
Servo Motor Control.
Flap position, which directs the flow of air through the system, is controlled by servo motors; these may be driven in either
a clockwise or anti-clockwise direction by signals from the A/ CCM. Motor, thus flap position, is monitored via a feedback
potentiometer which is situated within the motor housing.
Servo motors control the following flaps:

5.5. Press RECIRC button to instigate actuator check mode.
6. 6. Press FACE to cycle through the actu ator mode conditions 20 to 27.
7. 7. Press the FAN button to restore normal operation with default panel settings, ie AUTO @ 24°C.
Actuator Fault Codes
• NOTE: * The water valve operates on a 6 second pulse, ie 3 seconds ON, 3 seconds OFF.

Description and Operation
Fascia

The one-piece slush-moulded fascia has an injection-moulded ar mature and incorporates a steel transverse reinforcing rail.
Fascia side support brackets pre-set to th e BIW, determine fascia fore and aft, and height position s and a bush installed in a
BIW bracket centrally positioned on the upper fascia panel, similarly determines the correct transverse location of a fascia
dowel. These mountings together with access panels at each en d of the fascia and brackets at the top and sides of the BIW
tunnel, facilitate fascia removal and instal lation without the necessity for special tools or an alignment procedure. The fasci a
houses the main instrument panel, pass enger air bag module glovebox, air conditioning outlet vents and a centrally
mounted analogue clock, all of which can be readily removed wi thout disturbing the fascia. The fascia harness is located in
the nose of the fascia assembly to facilitate easy installati on in vehicle. The fascia must be removed from the vehicle to
access the harness.
Centre Console
The centre console is an injection moulded armature trimmed in matching ambla or leather with a wood veneer top finisher.
An iluminated smoker's compendium with pr ess and release lid is fitted at the rear of the 'J' gate. The centre section of the
console forms a deep stowage box with rear hinged lid which is padded to form a central arm rest. A hinged cup holder is
incorporated in the front end of the stowage box lid. A colour-keyed 'J' gate finisher surmounts the veneer top finisher and
the 'SPORT' mode and cruise control 'ON/OFF' selector switches are situated immediately to the rear of the 'J' gate. The rear
of the standard centre console houses a re ar air distribution grill and controls. On Daimler and 'Super 8' models, the centre
console incorporates a rear extensio n with rear seat heating controls.
