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
be
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.
