SEAT BELT SWITCH
DESCRIPTION
The seat belt switch is a small, normally open, sin-
gle pole, single throw, leaf contact, momentary
switch. Only one seat belt switch is installed in the
vehicle, and it is integral to the buckle of the driver
side front seat belt buckle-half, located on theinboard side of the driver side front seat track (Fig.
43). The seat belt switch is connected to the vehicle
electrical system through a two-wire pigtail wire and
connector on the seat belt buckle-half, which is con-
nected to a wire harness connector and take out of
the seat wire harness routed beneath the driver side
front seat cushion in the passenger compartment.
The seat belt switch cannot be adjusted or repaired
and, if faulty or damaged, the entire driver side front
seat belt buckle-half unit must be replaced.
OPERATION
The seat belt switch is designed to control a path
to ground for the seat belt switch sense input of the
ElectroMechanical Instrument Cluster (EMIC). When
the driver side front seat belt tip-half is inserted into
the seat belt buckle, the switch closes the path to
ground; and, when the driver side front seat belt tip-
half is removed from the seat belt buckle, the switch
opens the ground path. The switch is actuated by the
latch mechanism within the seat belt buckle.
The seat belt switch is connected in series between
ground and the seat belt switch sense input of the
instrument cluster. The seat belt switch receives
ground at all times through its pigtail wire connec-
tion to the seat wire harness from a take out of the
body wire harness. An eyelet terminal connector on
the body wire harness ground take out is secured
beneath a ground screw on the left cowl side inner
panel, beneath the instrument panel. The seat belt
switch may de diagnosed using conventional diagnos-
tic tools and methods.

CHECK VALVE
DESCRIPTION
A single washer system check valve is standard
equipment on this model, and is installed in the
washer system plumbing (Fig. 3). The check valve is
integral to the washer nozzle plumbing wye fitting
located in the cowl plenum area beneath the cowl
plenum cover/grille panel near the base of the wind-
shield. The check valve consists of a molded plastic
body with a raised arrowhead molded into its center
section that indicates the direction of the flow
through the valve, and three barbed hose nipples
formed in a wye configuration on the outside circum-
ference of the center section of the valve body. The
check valve cannot be adjusted or repaired and, if
faulty or damaged, it must be replaced.
OPERATION
The check valve provides more than one function
in this application. It serves as a wye connector fit-
ting between the engine compartment and washer
nozzle sections of the washer supply hose. It prevents
washer fluid from draining out of the washer supply
hoses back to the washer reservoir. This drain-back
would result in a lengthy delay from when the
washer switch is actuated until washer fluid was dis-
pensed through the washer nozzles, because the
washer pump would have to refill the washer plumb-
ing from the reservoir to the nozzles. Such a drain-
back condition could also result in water, dirt, or
other outside contaminants being siphoned into the
washer system through the washer nozzle orifice.
This water could subsequently freeze and plug thenozzle, while other contaminants could interfere with
proper nozzle operation and cause improper nozzle
spray patterns. In addition, the check valve prevents
washer fluid from siphoning through the washer noz-
zles after the washer system is turned Off.
When the washer pump pressurizes and pumps
washer fluid from the reservoir through the washer
plumbing, the fluid pressure unseats a diaphragm
from over a sump well within the valve by overriding
the spring pressure applied to it by a piston (Fig. 4).
With the diaphragm unseated, washer fluid is
allowed to flow toward the two washer nozzles. When
the washer pump stops operating, the spring pres-
sure on the piston seats the diaphragm over the
sump well in the valve and fluid flow in either direc-
tion within the washer plumbing is prevented. The
check valve cannot be adjusted or repaired and, if
faulty or damaged, it must be replaced.REMOVAL
(1) Remove both wiper arms from the wiper pivots.
(Refer to 8 - ELECTRICAL/WIPERS/WASHERS/
WIPER ARM - REMOVAL).
(2) Unlatch and open the hood.
(3) Remove the cowl plenum cover/grille panel
from over the cowl plenum. (Refer to 23 - BODY/EX-
TERIOR/COWL GRILLE - REMOVAL).
(4) From the underside of the cowl plenum cover/
grille panel, disconnect the cowl plenum and washer
nozzle hoses from the three barbed nipples of the
check valve (Fig. 5).
(5) Remove the check valve from the underside of
the cowl plenum cover/grille panel.
