2004 CHRYSLER VOYAGER air condition

(5) Pull the air filter straight down and out of the
HVAC housing (Fig. 2).
INSTALLATION
(1) Note the ªAirflowº directional arrow imprinted
on the foam seal around the frame of the air filter.
This arrow should always be oriented towards the
center of the vehicle.
(2) With the air filter ªAirflowº arrow properly ori-
ented, carefully slide the filter fully upward into the
HVAC housing through the air filter opening.
(3) With the latch still positioned against its
opened stop, reinstall the air filter door onto the
lower HVAC housing air filter opening.
(4) Slide the air filter door latch toward the front
of the vehicle until it hits the closed stop on the door.
AIR OUTLETS
DESCRIPTION
Based upon the system mode selected, conditioned
air can exit the front HVAC housing through one or a
combination of the four main housing outlets: defrost,
demist, panel, or floor. Once the conditioned air exits
the unit housing, it is directed through molded plas-
tic ducts to the various outlets in the vehicle interior.
These outlets and their locations are as follows:
²Defroster Outlet- A single, centrally mounted
outlet delivers air for defrosting the large windshield.
Because outlet vanes are not needed to direct flow, a
simple, integral grid is molded into the center of the
instrument panel top cover to prevent objects from
falling into the duct. If the defroster outlet is faultyor damaged, the instrument panel top cover must be
replaced.
²Demister Outlets- There are two side window
demisters that aid in defogging and defrosting the
front door windows. One demister outlet is located at
each outboard end of the instrument panel top pad,
near the belt line at the A-pillars. The demister out-
lets can be removed from the top pad individually for
service replacement.
²Instrument Panel Outlets- There are five
panel outlets in the instrument panel, one located
near each outboard end of the instrument panel fac-
ing the rear of the vehicle, and three located near the
top of the instrument panel center bezel. On models
with manual temperature control, all five of these
outlets are fully adjustable. On models with Auto-
matic Temperature Control (ATC) system, the center
outlet in the center bezel has fixed vanes because it
also houses the remote infrared temperature sensors
for the front seat positions. The outboard outlets can
be removed individually for service replacement. The
center bezel outlets are serviced as a gang of three
outlets and, on models with ATC, also includes the
infrared sensors.
²Front Door Rear Outlets- A fully adjustable
outlet located at the rear of each front door trim
panel supplies only cooled air to the intermediate
seat passengers. Air is supplied to these outlets from
the instrument panel through ducts in the doors that
use molded seals at the instrument panel to prevent
air leakage. The door ducts are integral to the front
door trim panels. These outlets also incorporate a red
reflector to improve the safety and visibility of an
opened front door to traffic approaching the vehicle
from the rear at night. These outlets can be removed
from the door trim panels for service replacement.
²Front Floor Outlets- There are two front floor
outlets, one located above each side of the floor panel
center tunnel below the instrument panel. These out-
lets are integral to the front HVAC distribution hous-
ing.
²Rear Floor Outlets- Wide rear floor outlets
located under each front seat have integral, fixed
directional dividers to distribute heated air across
the floor for intermediate seat passengers. These out-
lets are integral to the floor distribution ducts routed
under the front floor carpet from an outlet nozzle on
the bottom of the front HVAC distribution housing.

REMOVAL - CENTER BEZEL OUTLETS
The three outlets located near the top of the
instrument panel center bezel are serviced only as a
set of all three outlets. If the vehicle is equipped with

blower motor to regulate the blower motor ground
path it provides. The blower motor and wheel are
used to control the velocity of air moving through the
HVAC housing by spinning the blower wheel within
the housing at the selected speed or, in the ATC sys-
tem, at the selected or programmed speed.

For circuit descriptions and diagrams, refer to the
appropriate wiring information. The wiring informa-
tion includes wiring, diagrams, proper wire and con-
nector repair procedures, further details on wire
harness routing and retention, as well as pin-out and
location views for the various wire harness connec-
tors, splices and grounds.
BLOWER MOTOR ELECTRICAL DIAGNOSIS
(1) Check the fuse (Fuse 10 - 40 ampere) in the
Integrated Power Module (IPM). If OK, go to Step 2.
If not OK, repair the shorted circuit or component as
required and replace the faulty fuse.
(2) Turn the ignition switch to the On position. Be
certain that the A/C-heater control power is turned
on. Check for battery voltage at the fuse (Fuse 10 -
40 ampere) in the IPM. If OK, go to Step 3. If not
OK, check the front blower motor relay.
(3) Turn the ignition switch to the Off position.
Disconnect and isolate the battery negative cable.
Disconnect the front HVAC wire harness connector
for the front blower motor resistor block (Manual
Temperature Control) or the front blower motor
power module (Automatic Temperature Control) from
the resistor or module connector receptacle. Recon-
nect the battery negative cable. Turn the ignition
switch to the On position. Be certain that the A/C-
heater control power is turned on. Check for battery
voltage at the fused front blower motor relay output
circuit cavity of the front HVAC wire harness connec-
tor for the front blower motor resistor block (MTC) orthe front blower motor power module (ATC). If OK,
go to Step 4. If not OK, repair the open fused front
blower motor relay output circuit to the IPM as
required.
(4) Turn the ignition switch to the Off position.
Disconnect and isolate the battery negative cable.
Disconnect the front blower motor pigtail wire con-
nector from the connector receptacle of the front
blower motor resistor block (MTC) or the front
blower motor power module (ATC). Use jumper wires
to connect a battery and ground feeds to the blower
motor pigtail wire connector. The blower motor
should operate. If OK with MTC, proceed to diagno-
sis of the front blower motor resistor block (Refer to
24 - HEATING & AIR CONDITIONING/CONTROLS
- FRONT/BLOWER MOTOR RESISTOR - DIAGNO-
SIS AND TESTING). If OK with ATC, use a DRBIII
scan tool to diagnose the front blower motor power
module. Refer to Body Diagnostic information. If not
OK with MTC or ATC, replace the faulty front blower
motor.
BLOWER MOTOR NOISE OR VIBRATION
Refer to the Blower Motor Noise/Vibration Diagno-
sis chart for basic checks of the blower motor when a
vibration or noise is present (Fig. 7).

AIR OUTLETS
DESCRIPTION
Based upon the system mode selected, conditioned
air can exit the rear HVAC housing through one or a
combination of the two main housing outlets: air con-
ditioner, 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 floor heat duct to the intermediate and rear seat
occupants. The floor outlets are integral to the right
quarter trim panel and, if faulty or damaged, 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 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 headliner
bezels also feature a courtesy lamp, a fold-away coat
hook, and a fold-away assist handle. The overhead
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.
