Wiper Motor System - Chrysler Stratus RHD 1997 Interactive Electronic Service Manual

8K - 6 WINDSHIELD WIPERS AND WASHERS
DIAGNOSIS AND TESTING (Continued)
(4) If wipers will not run at low speed, using an
ohmmeter, check for open circuit. Check between ter-
minal 11 of the HI-LO wiper relay to Pin B of the
wiper motor wire harness connector for continuity. If
OK, go to Step 5. If not repair as necessary.
(5) If wiper will not run at the high speed, using
an ohmmeter, check for an open circuit. Check
between terminal 28 of the HI-LO wiper relay and
Pin A of the wiper motor wire harness connector for
continuity. If OK, go to Step 6. If not repair as nec-
essary.
(6) Check for faulty HI-LO wiper relay.
WIPERS RUN AT HIGH SPEED WITH SWITCH
IN LOW SPEED POSITION. WIPERS 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 jump start terminal and Pin B
on the wiper motor connector. Connect the second
lead between ground and Pin C on the wiper motor
connector (Fig. 6). If motor runs at low speed, go to
Step 3. If motor runs at high speed, replace the
motor.
(3) Check for faulty HI-LO wiper relay. Check for
crossed wires in harness from HI-LO relay to motor.
(4) Disconnect J3 14-way connector from the BCM
and remove the intermittent wiper relay.
(5) Using an ohmmeter, check for short to ground
Pin 8 of the J3 14–way connector.
(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 12 of the HI-LO wiper relay and
terminal 8 of the BCM J3 14-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.
Using a ohmmeter, Check Pin 8 of the BCM J3
14–way connector for continuity to ground signal
when the wipers are in the park position only.
(1) If no ground signal, test wiper motor.
(2) If a ground is received test the multi-function
switch.
(3) If the multi-function switch test OK, 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 D
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
C and Pin D 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 J3 14–way connector. Check for conti-
nuity between Pin D of the wiper motor wire harness
connector and terminal 2 of J3 14-way connector of
the BCM. If no continuity, repair as necessary. If con-
tinuity is OK, test the wiper motor.
WIPERS DO NOT RUN WHEN WASHER MOTOR
IS ENGAGED
(1) Disconnect the J3 14-way connector from the
BCM.
(2) Using a voltmeter, connect positive lead to ter-
minal 10 of the 14-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 motor and the BCM. Repair as
necessary.
(b) If the battery voltage, ensure that the
14–way connector is disconnected and check Pin 10
if it has 12 volts. If no voltage replace the BCM. If
battery voltage, test for a wiring short refer to
Group 8W, Wiring Diagrams.
WIPERS OPERATE IN INTERMITTENT
SETTINGS BUT DOES NOT HAVE SIX
DIFFERENT SPEEDS.
To test the multi-function windshield wiper switch,
refer to Group 8J, Turn Signals and Hazard Warning
Flashers, for diagnosis and testing of the Multi-Func-
tion Switch.

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 (Fig. 9).
