terminal D of the HI-LO wiper relay and terminal 3 of
the wiper motor body wire harness connector for con-
tinuity. If OK, go to step 6. If not repair as necessary.
(6) Check for faulty HI-LO wiper relay.
CONDITION: WIPERS RUN AT HIGH SPEED
WITH SWITCH IN LOW SPEED POSITION. WIP-
ERS OPERATE IN INTERMITTENT MODE, BUT
EACH WIPE IS AT HIGH SPEED.
(1) Disconnect motor connector.
(2) Using two jumper wires, connect one between the
battery positive terminal and terminal 4 of the motor
wire harness connect. Connect the second lead between
battery negative terminal and terminal 3 of the motor
wire harness connector (Fig. 12).
(a) If motor runs at low speed, go to step 3.
(b) If motor runs at high speed, check for crossed
wires in the motor pigtail wire connector.
(3) Check for faulty HI-LO wiper relay. Check for
crossed wires in harness from HI-LO relay to motor.
(4) Using an ohmmeter, check for short to ground.
Disconnect J3 24-way connector from the body control-
ler and remove the intermittent wiper relay.
(5) If none of the above conditions are present,
replace the body controller.
CONDITION: WIPERS RUN AT LOW SPEED
WITH SWITCH IN HIGH SPEED POSITION
(1) Check for faulty HI-LO wiper relay.
(2) Using an ohmmeter, check for open circuit be-
tween terminal C of the HI-LO wiper relay and termi-
nal 18 of the body controller J3 24-way connector. If
OK, go to step 3. If not OK, repair as necessary.
(3) Check wiper switch.
CONDITION: MOTOR WILL KEEP RUNNING
WITH SWITCH IN OFF POSITION.
(1) Check wiper motor body wiring harness for
shorts between the low speed motor feed terminal 3 or
high speed motor feed terminal 2 and battery or
ignition.
(2) Check for faulty wiper intermittent or HI/LO
relay.
(3) Check circuit from intermittent relay cavity B to
HI/LO relay cavity B for short to battery or ignition.
(4) Disconnect body controller J3 24-way connector.
Check circuit from terminal 1 of J3 24-way connector to
terminal C of the intermittent wiper relay for short to
ground.
(5) Using a voltmeter, connect positive lead to termi-
nal 16 of the body controller J3 24-way connector.
Connect negative lead to ground. If voltmeter reads
greater than 0 volts, check wiper switch and wiring.
(6) Using a voltmeter, connect positive lead to termi-
nal 10 of the body controller J3 24-way connector.
(a) If voltmeter reads 10 to 15 volts, check the
circuit for short to battery or ignition.
(b) If the voltmeter reads 0 volts, replace the body
controller.
CONDITION: WIPER WILL RUN CONTINU-
OUSLY WITH SWITCH IN THE INTERMITTENT
POSITION. WHEN COLUMN SWITCH IS
TURNED OFF, WIPERS STOP WHEREVER
THEY ARE, WITHOUT RETURNING TO PARK
POSITION.
(1) Check for ground at the wiper motor body wire
connector terminal 4.
(2) Using an ohmmeter, with the wiper motor in the
PARK position, check for continuity between terminal
2 and terminal 3 of the motor connector. If OK, go to
step 3. If not OK, replace motor.
(3) Check for continuity between terminal 1 of the
motor wire harness connector and terminal 2 of J3
24-way connector of the body controller. Using an
voltmeter, check for short circuit to a battery source or
ignition feed in this circuit.
WIPERS DO NOT RUN WHEN WASHER MOTOR
IS ENGAGED
(1) Disconnect the J3 24-way connector from the
body controller.
(2) Using a voltmeter, connect positive lead to termi-
nal 10 of the 24-way connector.
(3) Engage the washer switch so that the washer
motor runs continuously.
(a) If the voltage is zero, check the wiring between
the washer motor and the body controller. Repair as
necessary.
(b) If the voltage is 10 to 15 volts, replace the body
controller.
WIPER MOTOR REPLACEMENT
(1) Remove wiper arms and blades, disconnect hoses
from in-line connectors (Fig. 13). Be sure that the
in-line connector is saved.
(2) Remove the rear hood seal with the cowl top
plastic screen and disconnect the washer hose at in-
line connector. Save in-line connector.
(3) Disconnect motor connector at back side of hous-
ing.
(4) Remove four wiper housing module mounting
screws then remove housing.
(5) Remove nut and disconnect wiper drive link from
motor crank.
(6) Remove three motor mounting screws.
(7) Lift motor and mounting plate out of housing.
(8) Disconnect motor harness grommet from hous-
ing.
(10) For installation, reverse above procedures.
Tighten the motor crank nut to 11 to 14 N
I
m (89 to 124
in. lbs.) torque. Tighten the motor mounting screws to
11 to 12 N
I
m (89 to 106 in. lbs.) torque.
