WARNING: This page is about a different car, the 2016 Lincoln MKT. However, it is still accessible from the selected car via links, so may be relevant.
The auxiliary climate control housing is located on the LH side of the vehicle between the side windows and the floorpan, behind the rear wheel well. The driver has primary control of the auxiliary climate control system or can transfer control to a rear passenger control panel.
All of the auxiliary climate control system components are serviceable from the inside of the vehicle except the lines.
