INSTALLATION
(1) Install filter element by inserting the element
down directly into the element housing. The filter is
held in place by friction between the filter element
and the housing so no fasteners are used..
(2) Position windshield washer reservoir and
tighten bolts to 8 N·m ( 70 in. lbs.).
(3) Install passenger side cowl grill screen(Refer to
23 - BODY/EXTERIOR/COWL GRILLE SCREEN -
INSTALLATION).
(4) Close hood.
AIR FLOW DISTRIBUTION
DESCRIPTION
Based upon the system mode selected, conditioned
air can exit the standard heater-only or optional
heater-A/C unit housing through one or a combina-
tion of the three main housing outlets: defrost, panel
or floor. The defrost outlet is located on the top of the
housing, the panel outlet is located on the face of the
housing and the floor outlet is located on the bottom
of the housing. Once the conditioned air exits the
unit housing, it is further directed through molded
plastic ducts to the various outlets in the vehicle
interior (Fig. 27). These outlets and their locations
are as follows:
•
Defroster Outlet - A single large defroster out-
let is located in the center of the instrument panel
top cover, near the base of the windshield.
•
Side Window Demister Outlets - There are
two side window demister outlets, one is located at
each outboard end of the instrument panel top cover,
near the belt line at the A-pillars.
•
Panel Outlets - There are four panel outlets in
the instrument panel, one located near each outboard
end of the instrument panel facing the rear of the
vehicle and two located near the top of the instru-
ment panel center bezel.
•
Front Floor Outlets - There are four front
floor outlets, two located above each side of the floor
panel center tunnel near the dash panel.
•
Rear Floor Outlets - There are two rear floor
outlets, one located on each side of the floor panel
center tunnel near the front of each rear seat foot
well.
OPERATION
The defroster outlet receives airflow from the unit
housing through the molded plastic defroster duct,
which is snapped onto the unit housing defroster out-
let and secured by two tabs to mounting slots in the
dash panel. The airflow from the defroster outlet is
directed by fixed vanes in the defroster outlet grille
and cannot be adjusted. The defroster outlet grille is
integral to the instrument panel top cover.
The side window demister outlets receive airflow
from the unit housing through the air outlet distri-
bution duct, two molded plastic demister hoses and,
on the right side only, an intermediate duct. The air
outlet distribution duct is secured to the instrument
panel with screws and receives airflow through the
panel outlet of the unit housing. The airflow from the
side window demister outlets is directed by fixed
vanes in the demister outlet grilles and cannot be
adjusted. The side window demister outlet grilles are
integral to the instrument panel top cover.
The panel outlets also receive airflow from the unit
housing through the air outlet distribution duct.
Molded plastic panel outlet ducts and, on the left
side only, an intermediate elbow direct airflow from
the distribution duct to the outboard panel outlets,
while a center air outlet duct directs airflow from the
distribution duct to the two center panel outlets. The
airflow from each of the panel outlets is adjustable. A
knob in the center of each panel outlet grille is used
in a joystick fashion to adjust a center diffuser that
changes the airflow direction, and a knob on the
outer edge of each panel outlet grille opens or closes
a shutter to turn airflow on or off through that out-
let.
The front and rear floor outlets receive airflow
from the unit housing through the floor distribution
duct. The front floor outlets are integral to the
molded plastic floor distribution duct, which is
secured to the bottom of the unit housing. A molded
plastic rear seat duct elbow is fitted to the bottom of
the
floor distribution duct and directs airflow
