GENERAL
The auxiliary climate control system provides additional air conditioning for the second and third row seat occupants. The
auxiliary climate control system consists of:
An auxiliary climate control assembly.
A refrigerant circuit.
A heating circuit.
A distribution system.
An Auxiliary Climate Control Module (ACCM).
The Automatic Temperature Control Module (ATCM), of the main air conditioning system, is also used in the control of the
auxiliary climate control system. For additional information, refer to
Control Components
(412-04 Control Components)
Cabin air is recirculated through the auxiliary climate control assembly, where the air is temperature regulated and then
directed through the distribution system to registers in the roof, on the C pillars and on the left side of the loadspace. The
volume, temperature and distribution of the air from the auxiliary climate control assembly can be manually controlled by
the ACCM or automatically controlled by the ATCM.
