Customer states:
 The air conditioning does not cool.
Workshop findings:
 No DTCs are stored in the heating and air conditioning electronics control module, J255 (address word 0008).

Technical Background
The technical diagnosis reveals that
there is no refrigerant in the circuit. The
refrigerant hose that connects the
suction side of the compressor to the
condenser is found to be damaged, as
the rubber portion of the hose is making
contact with the compressor pulley
(Figure 1 and Figure 2).
A production issue with the assembly
gauge used during assembly of the
hose was found. This issue caused the
hose to be assembled with an incorrect

geometry. As a result, the lie intended
to keep the hose away from the air
conditioning compressor pulley was
compromised.

pulley.

Production Solution
The refrigerant hose assembly gauge was corrected in production.

Service
1. Replace the damaged refrigerant hose and ensure that the natural lie of the hose is away from the air
conditioning compressor pulley.
2. Evacuate and recharge the refrigerant circuit and replace any lost PAG oil that may have been discharged
from the system. Failure to maintain the correct total amount of PAG oil in the circuit will lead to premature air
conditioning compressor failure.
