Heating & A/C System: Notes
WARNING: This page is about a different car, the 2004 Dodge Dakota. However, it is still accessible from the selected car via links, so may be relevant.
CAUTION:
Do not remove the A/C-Heater Control Module from one vehicle and install it in another vehicle. The module's software configures differently for JTEC and NGC, and for vehicles with and without a CMTC. Failure to follow these instructions can either cause CMTC display problems or an inaccurate temperature to display. It can also cause an ambient temperature sensor open DTC to set when support should not be operative or it can completely prevent the A/C-Heater Control Module from reporting ambient temperature sensor circuit DTCs.
