Lincoln Aviator: Rear Climate Control / Description and Operation - Rear Climate Control - Overview
Overview
The
rear climate control system has controls selection located in the rear
of the floor console and the components located in the right rear
quarter panel by the D pillar. The temperature and controls breakdown
for the HVAC system is as follows, first row driver, first row passenger, second row seating temperature and third row seating temperature.
The
rear climate control system is standard equipment. The rear climate
control system operation is determined by the settings on the FCIMB control panel selection, the FDIM, the rear non touch screen RHVAC control panel or rear touch screen RACM control panel selection.
Both the rear non touch screen RHVAC control panel or rear touch screen RACM
allow rear climate operation and control. They include a power on and
off selection, a fan speed control selection, temperature control
selection, air distribution control selection, and a rear climate
control lock.
Through a setting in the RACM
the rear (third row) climate control system can be linked with the
second row climate system to have simultaneous control for both rows.
The rear system air can be cooled below interior air temperature only when A/C compressor operation has been requested by the settings of the climate control assembly of the FCIMB control panel or FDIM. The rear climate control system air can be heated at any time.
