A/C Heater Control Calibration
AZC System
If any of the motor actuators are replaced or the A/C, heater housing is replaced, the system should be recalibrated. This happens automatically at batteiy
disconnect or it can be accomplished using the DRB III. Without recalibration, the AZC head will not be sure of the actuators position and may result in
poor air control.
