Motor Will Keep Running With Switch In Off Position; Wipers Do Not Run When Washer Motor Is Engaged - Chrysler 2000 LHS Owner's Manual

8K - 8 WIPER AND WASHER SYSTEMS
DIAGNOSIS AND TESTING (Continued)
(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.

WARNING: ON VEHICLES EQUIPPED WITH AIR-
BAGS, SEE GROUP 8M, RESTRAINT SYSTEMS FOR
STEERING WHEEL OR COLUMN REMOVAL PROCE-
DURES.
Whenever a wiper motor malfunction occurs, dis-
connect motor wire harness and clean the terminals.
Ensure the wire harness is properly connected before
starting diagnosis and repair procedures. Refer to
Wiper Motor Test table.
