AIR OUTLETS
DESCRIPTION
Based upon the system mode selected, conditioned
air can exit the rear heater-A/C unit housing through
one or a combination of the two main housing out-
lets: air conditioner, or heater. Once the conditioned
air exits the unit housing, it is directed through
molded plastic ducts to the various outlets in the
vehicle interior. These outlets and their locations are
as follows:
²Floor Outlets- Three floor outlets with fixed
vanes are located in the right quarter trim panel,
near the floor. These outlets distribute air from the
rear heater distribution duct to the intermediate and
rear seat occupants. The floor outlets are integral to
the right quarter trim panel and, if faulty or dam-
aged, the quarter trim panel must be replaced.
²Overhead Outlets- Four (two right side and
two left side) fully adjustable outlets along the roof
rails distribute air from the rear A/C distribution
duct and the headliner ducts to the intermediate and
rear seat occupants. The headliner ducts are integral
to the headliner panel. Each overhead outlet is
housed in a headliner bezel. The two forward head-
liner bezels also feature a courtesy lamp, a fold-away
coat hook, and a fold-away assist handle. The over-
head outlets can be removed from the headliner
bezels individually for service replacement.
REMOVAL
(1) Using a trim stick or another suitable wide
flat-bladed tool, gently pry the thumb wheel end of
the overhead outlet away from the pivot pin in the
headliner bezel until one end of the outlet is released
(Fig. 1).(2) Pull the opposite end of the overhead outlet
away from its pivot pin in the headliner bezel until
that end of the outlet is released.
(3) Remove the overhead outlet from the opening
in the headliner bezel.
INSTALLATION
(1) Position the overhead outlet into the opening in
the headliner bezel.
(2) Slide the non-thumb wheel end of the outlet
onto the pivot pin in the headliner bezel. Using hand
pressure, push the thumb wheel end outboard onto
the pivot pin until it fully seats.
