WARNING: This page is about a different car, the 2016 Ford Expedition. However, it is still accessible from the selected car via links, so may be relevant.
The auxiliary climate control system has dual controls for the front and rear passengers consisting of temperature, mode and blower speed. The front auxiliary control functionality is integrated into the HVAC control module. All auxiliary climate control components are hard wired to the HVAC control module. The rear auxiliary control panel, known as the RHVAC module, communicates with the front system over the MS-CAN. For illustrations and auxiliary climate control button operation information, refer to the Owner's Literature.
