VACUUM CHECK VALVE
DESCRIPTION
On models with a gasoline engine, a vacuum check
valve is installed in the accessory vacuum supply line
near the vacuum tap on the right side of the engine
intake manifold. On models with a diesel engine, a
vacuum check valve is installed on the engine vac-
uum pump. The vacuum check valve is designed to
allow vacuum to flow in only one direction through
the accessory vacuum supply circuits.
OPERATION
The use of a vacuum check valve helps to maintain
the system vacuum needed to retain the selected
HVAC mode and vehicle speed control settings. On
gasoline engine models, it prevents the engine from
bleeding down system vacuum through the intake
manifold during extended heavy engine load (low
engine vacuum) operation. On diesel engine models,
it prevents oil from contaminating the vacuum sup-
ply system by maintaining vacuum in the pump after
the engine is shut-off.
On gasoline engine models, a second vacuum check
valve is installed in the accessory vacuum supply line
at the tee fitting near the dash panel in the engine

compartment. This check valve also helps to main-
tain the system vacuum needed to retain the selected
HVAC mode settings, but isolates the HVAC vacuum
circuit from the vehicle speed control vacuum circuit.
It prevents the vehicle speed control servo from
bleeding down the HVAC system vacuum during
extended heavy engine load operation.
The vacuum check valve cannot be repaired and, if
faulty or damaged, it must be replaced.
REMOVAL
(1) On models with a gasoline engine, unplug the
vacuum supply line connector at the vacuum check
valve (Fig. 28). On models with a diesel engine,
remove the clamp from the vacuum supply line con-
nector and unplug the connector from the vacuum
check valve (Fig. 29).
(2) On models with a gasoline engine, note the ori-
entation of the check valve in the vacuum supply line
for correct reinstallation.
(3) On models with a gasoline engine, unplug the
remaining line on the vacuum check valve from the
vacuum supply line fitting. On models with a diesel
engine, unscrew the check valve and nipple unit from
the engine vacuum pump.
INSTALLATION
(1) On models with a gasoline engine, plug in the
vacuum check valve to the vacuum line fittings, not-ing the proper orientation of the check valve in the
line. On models with a diesel engine, screw the check
valve and nipple unit into the engine vacuum pump.
Tighten the check valve and nipple unit to 24 N´m
(18 ft. lbs.).
(2) On models with a diesel engine, plug in the
connector to the vacuum check valve and install the
clamp from the vacuum supply line connector.
VACUUM RESERVOIR
DESCRIPTION
Models equipped with a gasoline engine have a
vacuum reservoir. The vacuum reservoir is mounted
in the passenger side cowl plenum area, under the
cowl plenum cover/grille panel. The cowl plenum cov-
er/grille panel must be removed from the vehicle to
access the vacuum reservoir for service.
OPERATION
Engine vacuum is stored in the vacuum reservoir.
The stored vacuum is used to operate the vacuum-
controlled vehicle accessories during periods of low
engine vacuum such as when the vehicle is climbing
a steep grade, or under other high engine load oper-
ating conditions.
The vacuum reservoir cannot be repaired and, if
faulty or damaged, it must be replaced.

DESCRIPTION - HVAC SYSTEM AIRFLOW
Outside air enters the vehicle through the cowl top
opening at the base of the windshield, and passes
through a plenum chamber to the HVAC system blower
housing (Fig. 1). Air flow velocity can then be adjusted
with the blower motor switch on the a/c heater control
panel. The air intake openings must be kept free of
snow, ice, leaves, and other obstructions for the HVAC
system to receive a sufficient volume of outside air.
It is also important to keep the air intake openings
clear of debris because leaf particles and other debris
that is small enough to pass through the cowl plenum
screen can accumulate within the HVAC housing. The
closed, warm, damp and dark environment created
within the HVAC housing is ideal for the growth of cer-
tain molds, mildews and other fungi. Any accumulation
of decaying plant matter provides an additional food
source for fungal spores, which enter the housing with
the fresh air. Excess debris, as well as objectionable
odors created by decaying plant matter and growing
fungi can be discharged into the passenger compart-
ment during HVAC system operation.

BLOWER MOTOR
DESCRIPTION
The blower motor and blower wheel are located in
the passenger side end of the HVAC housing, below
the glove box. The blower motor controls the velocity
of the air flowing through the HVAC housing by spin-
ning a squirrel cage-type blower wheel within the
housing at the selected speed. The blower motor and
blower wheel can be serviced from the passenger
compartment side of the housing.
OPERATION
The blower motor will only operate when the igni-
tion switch is in the On position, and the a/c heater
mode control switch knob is in any position, except
Off. The blower motor receives a fused battery feed
through the blower motor relay whenever the igni-
tion switch is in the On position.
The blower motor battery feed circuit is protected
by a fuse in the Power Distribution Center (PDC).
The blower motor relay control circuit is protected by
a fuse in the junction block. Blower motor speed is
controlled by regulating the ground path through the
a/c heater mode control switch, the blower motor
switch, and the blower motor resistor.
The blower motor and blower wheel cannot be
repaired and, if faulty or damaged, they must be
replaced. The blower motor and blower wheel may be
serviced separately, although if the motor is to be
replaced, a blower wheel will come as part of a pre-
balanced assembly.

Possible causes of the blower motor not operating
in all speeds include:
²Faulty fuse
²Faulty blower motor switch
²Faulty blower motor resistor
²Faulty blower motor relay
²Faulty blower motor circuit wiring or wire har-
ness connectors.
VIBRATION
Possible causes of blower motor vibration include:
