TORQUE SPECIFICATIONS
An optional auxiliary air conditioning and heating system 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.

The auxiliary A/C and heating system has the following features
- The auxiliary A/C and heating system is functional whenever the instrument panel mounted A/C control is in any position except OFF.
- The auxiliary blower motor recirculates the air inside the vehicle. Outside air is not available to the auxiliary system.
- Air is cooled and dehumidified by the auxiliary A/C evaporator core only if the instrument panel mounted A/C control is adjusted to a position that requires A/C compressor operation.
- The temperature blend door and the auxiliary mode door are controlled by electric actuator motors.
- Movement of the auxiliary temperature control between COOL and WARM causes a corresponding movement of the temperature blend door to mix air flowing through and around the auxiliary heater core.
- Movement of the auxiliary mode control between PANEL and FLOOR causes a corresponding movement of the auxiliary mode door to direct air flow between the panel (headliner) registers and the floor duct.
