Auxiliary Climate Control: Notes
An optional heater and air conditioning assembly (18D283) is available. The system is a one-piece unit that is located on the RH side of the vehicle between the side windows and the floorpan, behind the rear wheel well. The driver has primary control of the auxiliary air conditioning and heating system or can transfer control to a rear passenger control panel.
All of the auxiliary A/C-heater system components are serviceable from the inside of the vehicle except the lines.
