DESCRIPTION
Some customers may complain that it is difficult to adjust the cabin temperature using the auto A/C. This
may be more noticeable when the outside temperature is approximately 50 degrees Fahrenheit (10
Celsius).
Customer comment samples:



The cabin temperature does not decrease to the customers desire (i.e. the set temperature on the
temperature control dial). It is warmer in the vehicle cabin than the selected temperature.
Even if adjusting the set temperature on the temperature control dial to decrease the cabin
temperature, the air conditioner always blows warm air from the vents.
When the outside temperature is approximately 50 degrees Fahrenheit (10 Celsius) as the seasons
change, the customer first sets the temperature control dial to 72 degrees Fahrenheit (22 Celsius)
to warm up the cabin. After the cabin temperature increases too warm, the customer decreases the
set temperature but the vent air temperature does not change as expected and remains too warm.
If it is adjusted to "Max. Cold" then too much cold air blows out and it is difficult to adjust the cabin
temperature.
The climate control unit logic has been changed to correct this concern.
Customers having this concern should have their vehicle repaired using the following repair procedure.
REPAIR PROCEDURE
1. Verify customer concern.
