Service Information
Effective after February 16, 2004; the Climate Control Personalization feature on vehicles equipped with Automatic Temperature Control (RPO CJ2)
will not be an available content option. The operator will not be able to recall any climate control memory settings for Driver 1 and Driver 2 when the
selection on the DIC (Driver Information Center) is set for memory recall "key fob" and "key in ignition", or when the memory buttons on the door are
depressed.
NOTE:
Prior to servicing the HVAC Control Module, determine the part number by using a scan tool, such as the TECH 2.
This modification to the vehicle's personalization features is a result of a calibration change to the HVAC control module. The modified, 2nd design
HVAC control module can be identified by P/N 8-15132-070-0. The HVAC settings on this new modified control module will always default to the
settings last used.
AIPDN will continue to supply the 1st design HVAC control module for those vehicles currently equipped with the Climate Control Personalization
feature.
