4 Plenum

Climate Control: Air Distribution:

Fresh air is drawn-in via the plenum to the left- and right-hand blower units, which are ducted to the heater/air conditioning unit. The air is then heated or cooled as required and delivered to the selected air outlets. After passing through the cabin, the air enters the trunk and is exhausted from the vehicle through vents under each rear wheel arch.

The air distribution system includes:
- Connecting ducts between the left- and right-hand blower units and the heater/air conditioning unit.
- Front and side window demist/defrost ducting integral with the fascia panel.
- Ducting to the front footwell.
- Ducting to the left- and right-hand fascia air outlets.


The air conditioning and heater unit is located centrally behind the fascia. The air intake plenum houses an optional particle filter which is held in place by clips moulded on the filter housing. The filter is effective at removing particles above 3.5 microns.

Airflow is achieved by using two blower units, one either side of the air conditioning unit casing, which are ducted from a common fresh air intake. The two blower motors are controlled at variable speeds by the Air Conditioning Control Module (A/CCM). They are regulated by power transistor modules which provide linear variation of blower speed. The two blower motors are inhibited when the engine coolant temperature is below 30 °C (86 °F) and heating is requested. Air passes through the car to the trunk, venting under each rear wheel arch.
