Rear overhead air conditioner


A rear overhead air conditioning unit is an available option to supplement the output of the front air conditioner, for increased rear seat passenger comfort.

This unit includes a roof-mounted evaporator coil and a blower motor with a wide squirrel-cage type blower wheel. A four position (three speeds plus off) rear blower motor switch is mounted in the headliner behind the right front seat position, where it is accessible to both the driver and the second seat passengers.


The wide and shallow rear unit is positioned between the front and second seats to provide ample headroom for all vehicle occupants. The headliner is molded to cover the unit and includes an integral air intake grille toward the front of the unit, and an opening for a snap-in outlet bezel that includes four adjustable outlet barrels toward the rear of the unit.

A condensate tray is integral to the lower unit housing, and water is drained out of the unit through hoses located behind the trim on each of the B-pillars.

The rear overhead air conditioner will provide cooling only when an air conditioning mode is selected with the front heater and A/C controls, but the rear blower will operate independent of the front controls to circulate the interior air if desired.
