A/C-Heater System
WARNING: This page is about a different car, the 2002 Dodge Stratus and 2002 Chrysler Sebring. However, it is still accessible from the selected car via links, so may be relevant.
Any time negative battery cable is disconnected or battery voltage to Body Control Module (BCM) is less than 10 volts, blend, mode and recirculation door actuators for A/C and heater system must be recalibrated. Prior to replacing suspect part, disconnect negative battery cable for one minute. This will automatically initiate calibration.
