8R - 8 WIPERS/WASHERS
WIPERS/WASHERS (Continued)
(3) Check for faulty HI-LO wiper relay. Check for
crossed wires in harness from HI-LO relay to motor.
(4) Disconnect C3 bone 12-way connector from the
BCM and remove the HI/LO wiper relay.
(5) Using an ohmmeter, check terminal 12 of the
C3 bone 12-way connector for short to ground.
(6) If continuity to ground is present, repair as
necessary. If no continuity to ground, replace the
BCM.
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
between terminal C of the HI-LO wiper relay and
terminal 12 of the BCM 33 bone 12-way connector. If
OK, go to Step 3. If not OK, repair as necessary.
(3) Check wiper switch.
(4) Check for binding linkage
(5) Refer to MOTOR RUNS SLOWLY AT ALL
SPEEDS.
MOTOR WILL KEEP RUNNING WITH SWITCH IN
OFF POSITION.
(1) Check wiper motor wiring harness for shorts
between the low speed motor feed terminal 2 or high
speed motor feed terminal 1 and battery or ignition.
(2) Check for faulty wiper ON/OFF or HI/LO relay.
(3) Check circuit from ON/OFF relay terminal C to
HI/LO relay terminal B for short to battery or igni-
tion.
(4) Disconnect the C3 bone 12-way connector from
the BCM. Check circuit from terminal 4 of C3 bone
12-way connector to terminal C of the ON/OFF wiper
relay for short to ground.
(5) Check circuit from terminal 3 of C2 bone
24–way connector to Pin 4 of the wiper motor har-
ness connector for an open. If open circuit, repair as
necessary.
(6) Using a voltmeter, connect positive lead to ter-
minal 8 of the C2 black 24-way connector. Connect
negative lead to ground. If voltmeter reads greater
than 0 volts, check wiper switch and wiring.
(7) Using a voltmeter, connect positive lead to ter-
minal 8 of the C3 black 12-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
BCM.
WIPER WILL RUN CONTINUOUSLY WITH SWITCH
IN THE INTERMITTENT POSITION. WHEN COLUMN
SWITCH IS TURNED OFF, WIPERS STOP
WHEREVER THEY ARE, WITHOUT RETURNING TO
PARK POSITION.
(1) Using an ohmmeter, check for ground at Pin 4
on the wiper motor connector. If grounded, replace
motor.
(2) Using an ohmmeter, with the wiper motor in
the PARK position, check for continuity between Pin
5 and Pin 4 on the wiper motor connector. If contin-
uous continuity, go to Step 3. If not OK, replace
motor.
(3) Disconnect the wiper motor wire harness con-
nector and the BCM C3 bone 12–way connector.
Check for continuity between Pin 1 of the wiper
motor wire harness connector and terminal 3 of the
BCM C3 bone 12-way connector. If no continuity,
repair as necessary. If continuity is OK, test the
wiper motor.
WIPERS DO NOT RUN WHEN WASHER MOTOR IS
ENGAGED
(1) Disconnect the C2 black 24-way connector from
the BCM.
(2) Using a voltmeter, connect positive lead to ter-
minal 7 of the C2 black 24-way connector and the
negative lead to ground.
(3) Engage the washer switch so that the washer
motor runs continuously.
(a) If the voltage is zero, check the wiring
between the washer switch terminal 2 and the
BCM and repair as necessary.
(b) If the battery voltage is shown, replace the
BCM.
HEADLAMP WASHERS -

DESCRIPTION
Headlamp washers are available as a factory-in-
stalled option on this model. The headlamp washers
on this vehicle work in conjunction with the wind-
shield washers. The headlamp washers are enabled
with the headlamps "ON" and the windshield wash-
ers activated. With the windshield washers activated
the headlamp washers will spray for a preset amount
of time controlled by a relay.
