Initial publication

• The customer may report that after a specific temperature is selected in AUTO mode, the resulting airflow and
temperature are uncomfortable.
Tip: The customer complaint is subjective and may be difficult to diagnose during a road test. Perform a
test drive with the customer both before and after this repair to ensure a thorough understanding of the
customer’s concern.
• DTCs for mechanical malfunction of one or more air distribution control motors may be stored in the air
conditioning/heating control unit, J255 (address word 08).

Technical Background
At certain outside temperatures and in certain operating conditions, the temperature in the passenger
compartment fluctuates. This fluctuation is caused by the unventilated sensor in the air conditioning control panel.

Production Solution
The sensitivity of the passenger compartment has been optimized. New software in the air conditioning/heating
control unit, J255 (and in the rear air conditioning/heating control unit, J265, if equipped) addresses the condition.
