INTERMITTENT WIPER MOTOR SYSTEM TEST
Intermittent Wiper Motor Service Procedures for
diagnosis of problems which do not involve the delay
function, refer to the Two-Speed Motor Function
Tests. The two-speed functions of all wiper motors
are identical.
If a problem occurs, only in the DELAY mode, the
following tests are to be performed.
INTERMITTENT WINDSHIELD WIPER SWITCH
TESTS
WARNING: ON VEHICLES EQUIPPED WITH AIR-
BAG, SEE GROUP 8M, RESTRAINT SYSTEMS FOR
STEERING WHEEL OR COLUMN REMOVAL PROCE-
DURES.
The intermittent wipe function on AC, AG, AJ and
AY vehicles is controlled by the body controller, lo-
cated in the passenger compartment behind the right
side kick panel (Fig. 22). If the body controller is de-
termined to be the problem, refer to Group 8E, In-
strument
Panels
and
Gauges,
for
replacement
procedures.
CONDITION: WIPERS DO NOT COME ON
WHEN THE SWITCH IS IN DELAY POSITION
PROCEDURE
(1) Disconnect 25-way connector (blue) from the
body controller.
(2) Place wiper control switch in maximum DE-
LAY position.
(3) Connect positive lead of voltmeter to pin 9 of
connector (blue) and negative lead to the good
ground.
(a) If voltmeter reads 0, check control switch and
wiring for an open circuit.
(b) If voltmeter reads 10 to 15 volts, proceed to
step 4.
(4) Connect positive lead of voltmeter to pin 22 of
blue connector and negative lead to a good ground.
(a) If voltmeter reads 0, check fuses and wiring
for an open circuit.
(b) If voltmeter reads 10 to 15 volts, reconnect
body controller and proceed to step 5.
(5) Connect positive lead of voltmeter to pin 24 of
blue connector and negative lead to the metal case of
the body controller. Disconnect wiring harness from
wiper motor. Set control switch to the minimum de-
lay mode.
(a) If voltmeter reads 0, check wiring from the
intermittent wipe switch to body controller for an
open circuit.
(b) If voltmeter reads 10 to 15 volts, proceed to
step 6.
(6) Connect voltmeter to pin L of the Intermittent
wiper switch. Place intermittent wiper switch in the
Max. Delay position.
(a) If voltmeter reads zero volts, change the in-
termittent wiper switch.
(b) If voltmeter reads 10-15 volts, check the wir-
ing harness from the intermittent wiper switch to
the wiper motor for an open circuit.
(7) If all tests above have been performed and the
problem was not found, replace the body controller.

CONDITION: WIPERS START TO WIPE, BUT
STOP BEFORE ONE COMPLETE CYCLE AND
DO NOT RETURN TO PARK POSITION
PROCEDURE
(1) Verify that motor will park when the column
switch is put in the OFF position.
(2) Set wiper control switch to maximum DELAY
and allow motor to run until it stops during the wipe
cycle. When motor stops, disconnect 25-way blue con-
nector from the body controller.
(3) Connect positive lead of voltmeter to pin 20 of
blue connector and negative lead to the metal case of
the body controller.
(a) If voltmeter reads 0, check wiring for an open
circuit.
(b) If voltmeter reads 10 to 15 volts, proceed to
step 4.
(4) Using an ohmmeter or continuity tester;
(a) Check for continuity between pins 20 and 24
of blue connector of the body controller.
(b) Reverse ohmmeter leads on pins 20 and 24,
again checking for continuity.
(c) If continuity between pins 20 and 24 is not
observed in both steps a and b, replace the body
controller.
CONDITION: EXCESSIVE DELAY OF MORE
THAN 30 SECONDS OR INADEQUATE
VARIATION IN DELAY
PROCEDURE
(1) Variations in delay should be as follows:
(a) Minimum delay control to extreme counter-
clockwise position before first detent of 1/2 to 2 sec-
onds.
(b) Maximum delay control to extreme clockwise
position before OFF detent of 15 to 25 seconds.
(2) If there is excessive delay or no variations in
delay, remove the wiper motor wiring harness while
the motor is parked in the OFF position.
(3) Remove 25-way blue connector from the body
controller.
(4) Set wiper control switch to maximum DELAY
position.
(5) With ignition switch in ON position, measure
voltage between pin 9 of black connector and a good
ground.
(a) If voltmeter reads 0, proceed to step 6.
(b) If voltmeter reads 10 to 15 volts, proceed to
step 7.
(6) Set wiper control switch to minimum DELAY
position and measure voltage between pin 9 of blue
connector and a good ground. If voltmeter reads 0,
check for an open circuit in the intermittent wipe
wiring harness.
(7) Remove wiper motor circuit fuse.
(8) Using an ohmmeter, measure the resistance be-
tween pins 9 and 22 of the body controller 25-way
black connector. Set the wiper control switch first to
minimum DELAY and then maximum DELAY.
(a) If resistance reading at minimum DELAY
setting is between 0 and 15 ohms, and at maxi-
mum DELAY setting the resistance is between
240,000 and 400,000 ohms, replace the body con-
troller.
(b) If the resistance values above are not ob-
tained, replace the wiper control switch.
CONDITION: WIPERS DO NOT RUN
CONTINUALLY WHEN WASH CONTROL IS
OPERATED DURING DELAY MODE
PROCEDURE
(1) Disconnect 25-way blue connector from the
body controller
(2) Using a voltmeter, connect the positive lead to
pin 10 of the (Black) connector. Connect negative
lead to the body computer metal case.
(3) Set wiper control switch to DELAY position.
(4) Depress wash switch.
(5) If voltage reads 0, check switch relay and wir-
ing.
(6) If voltage is between 10 and 15 volts, the prob-
lem is in the body controller.
CONDITION: IN DELAY MODE, WIPERS RUN
CONTINUALLY WHEN WASH IS OPERATED
BUT DO NOT PROVIDE FOUR EXTRA WIPES
WHEN WASH CONTROL IS RELEASED
PROCEDURE
Replace body controller.
CONDITION: WIPERS START ERRATICALLY
DURING DELAY MODE
PROCEDURE
(1) Verify that the ground connection at the in-
strument panel is making a good connection, free
from paint and is tight.
(2) Verify that the motor ground strap is making
good contact and that the motor mounting bolts are
tight.
(3) Verify that the wiring connections to the body
controller, wiper motor, and wiper motor switch are
tight and free of corrosion.
(4) If condition is not corrected, problem is with
the body controller

strument panel is making good connection, free from
paint and is tight.
(2) Verify that the motor ground strap is making
good contact and that the motor mounting bolts are
tight.
(3) Verify that the wiring ground connections for
the intermittent wipe control unit and the wiper
switch are tight.
(4) If condition is not corrected, replace control
unit.
STANDARD WIPER SWITCH TEST
AP BODY
To test the switch, first disconnect the switch wires
from the body wiring in the steering column. Using
an ohmmeter, test for continuity between the termi-
nals of the switch, as indicated in the following con-
tinuity chart. The identity of each terminal is shown
in Fig. 23.
INTERMITTENT WIPE SWITCH TEST
AC AND AY BODIES
To test the switch, first disconnect the switch wires
from the body wiring in the steering column. Using
an ohmmeter, test for continuity between the termi-
nals of the switch, as indicated in the following con-
tinuity chart. The identity of each terminal is shown
in Fig. 24.
For test purposes, the first position is the OFF po-
sition, next is the slide for the DELAY wipe. LOW is
the next detent position and HIGH is the full coun-
terclockwise detent position.
In any wiper mode, if the knob is pushed all the
way in, the washer circuit will be completed.
AG AND AJ BODIES
To test the switch, remove switch pod from instru-
ment panel. Using an ohmmeter, test for continuity
between the terminals of the switch, as indicated in
the following continuity chart (Fig. 25).
