The controls for the climate control system are in one or more locations depending on vehicle option content:
The customer inputs are directly inputted in to the Dual Automatic Temperature Control (DATC) module.
When A/C is selected, the HVAC control module sends the request to the BCM over the Medium Speed Controller Area Network (MS-CAN). The BCM then sends the request to the PCM over the High Speed Controller Area Network (HS-CAN).
On vehicles with Sony® Sound the touch screen and voice commands can be used for climate control inputs.
