DOOR AJAR SWITCH

DESCRIPTION

The door ajar switches, located in each door pillar,

are a self-adjusting, spring loaded plunger. The other
end of the switch is actuated by the hinge face of the
door. The self adjusting feature of the switch plunger
is a one-time feature, it can be adjusted inward (com-
pressed),

but

cannot

readjusted

outward

(extended) once it has been compressed. This nor-
mally open switch only closes when the door is open.

The door ajar switch cannot be repaired and, if

faulty or damaged, it must be replaced.

OPERATION

The door ajar switches control a path to ground

through separate driver and passenger door ajar
switch sense circuit inputs to the instrument cluster
chime warning circuitry when a door is opened. The
door ajar switch inputs to the instrument cluster can
be diagnosed using conventional diagnostic tools and
methods.

DIAGNOSIS AND TESTING - DOOR AJAR
SWITCH

WARNING: ON VEHICLES EQUIPPED WITH AIR-
BAGS, DISABLE THE AIRBAG SYSTEM BEFORE
ATTEMPTING ANY STEERING WHEEL, STEERING
COLUMN, OR INSTRUMENT PANEL COMPONENT
DIAGNOSIS OR SERVICE. DISCONNECT AND ISO-
LATE THE BATTERY NEGATIVE (GROUND) CABLE,
THEN WAIT TWO MINUTES FOR THE AIRBAG SYS-
TEM CAPACITOR TO DISCHARGE BEFORE PER-
FORMING FURTHER DIAGNOSIS OR SERVICE. THIS
IS THE ONLY SURE WAY TO DISABLE THE AIRBAG
SYSTEM. FAILURE TO TAKE THE PROPER PRE-
CAUTIONS COULD RESULT IN ACCIDENTAL AIR-
BAG DEPLOYMENT AND POSSIBLE PERSONAL
INJURY.

(1) Disconnect the negative battery cable. Remove

the door ajar switch from the door hinge pillar. Dis-
connect the wire harness connector from the door
ajar switch. Check for continuity between the door
ajar switch output and the driver or passenger door
ajar switch sense circuit in the door ajar switch con-
nector. There should be continuity with the switch
plunger released, and no continuity with the switch
plunger depressed. If OK, go to Step 2. If not OK,
replace the faulty door ajar switch.

(2) Check for continuity between the door ajar

switch output circuit of the wire harness connector
for the driver or passenger door ajar switch and a
good ground. There should be continuity. If OK, go to
Step 3. If not OK, repair the open door ajar switch
output circuit to ground as required.

(3) Remove the instrument cluster from the instru-

ment panel. Disconnect the instrument panel wire
harness

connector

from

the

instrument

cluster.

Check for continuity between the driver or passenger
door ajar switch sense circuit of the wire harness
connector for the driver or passenger door ajar switch
and a good ground. There should be no continuity. If
OK, go to Step 4. If not OK, repair the shorted driver
or passenger door ajar switch sense circuit between
the door ajar switch and the instrument cluster as
required.

(4) Check for continuity between the driver or pas-

senger door ajar switch sense circuit of the wire har-

ness connector for the driver or passenger door ajar
switch and the wire harness connector for the instru-
ment cluster. There should be continuity. If not OK,
repair the open driver or passenger door ajar switch
sense circuit between the door ajar switch and the
instrument cluster as required.

REMOVAL

(1) Disconnect the negative battery cable
(2) Unlatch and open the door fully.
(3) Using

small

screwdriver,

pry

carefully

between the hinge pillar and the outer circumference
of the door ajar switch housing to release the switch
snap features from the mounting hole in the pillar.

(4) Pull the door ajar switch out through the

mounting hole in the hinge pillar far enough to
access and disconnect the wire harness connector
from the door ajar switch.

(5) Remove the door ajar switch from the door

hinge pillar.

INSTALLATION

(1) Position the door ajar switch to the door hinge

pillar.

(2) Connect the wire harness connector to the door

ajar switch.

(3) Guide the wire harness for the door ajar switch

and the receptacle end of the switch into the mount-
ing hole in the door hinge pillar.

(4) Using hand pressure, press the door ajar

switch housing into the mounting hole in the door
hinge pillar until the snap features of the switch are
fully engage in the mounting hole.

(5) Slowly close the door and allow the door ajar

switch plunger self-adjuster mechanism to ratchet to
the proper position.

(6) Reconnect the negative battery cable.
(7) Open and close the door to verify proper door

ajar switch operation.
