DIAGNOSIS AND TESTING (Continued)
Fig. 7 Body Control Module 22-Way Connector
(11) Disconnect motor connector and replace fuse
15 from the Junction Block.
(a) If fuse does not blow, go to Step 2.
(b) If fuse blows, wiper control circuit is at fault,
repair as necessary, refer to Group 8W, Wiring Dia-
grams.
MOTOR RUNS SLOWLY AT ALL SPEEDS
(1) Disconnect the wire harness from the wiper
motor. Remove wiper arms and blades. Disconnect
motor drive link from motor. Connect an ammeter
between battery negative jump start terminal and
Pin C on the wiper motor connector (Fig. 5). Connect
battery positive wire to Pin B on the wiper motor
connector. When replacing drive link nut tighten to
11 to 12 N·m (98 to 106 in. lbs.) torque.
(a) If average ammeter reading is more than 6
amps, replace motor.
(b) If motor runs and average ammeter reading
is less than 6 amps, go to Step 2.
(2) Check to see if wiper linkage or pivots are
binding or caught.
MOTOR WILL RUN AT HIGH SPEED, BUT NOT
MOVE AT LOW SPEED. MOTOR WILL RUN AT
LOW SPEED, BUT WILL NOT MOVE AT HIGH
SPEED
(1) Disconnect motor connector.
(2) If motor will not run on low speed, connect a
jumper wire between battery positive jump start ter-
minal and Pin B on the wiper motor connector. Con-
nect a second jumper wire between ground and Pin C
on the wiper motor connector (Fig. 5).
(a) If motor runs, go to Step 3.
(b) If motor does not run, replace the motor.
(3) If motor will not run on high speed, connect a
jumper wire between battery positive remote cable
terminal and Pin A. Connect a second jumper wire
between ground and Pin C of the motor connector.
(a) If motor runs, go to Step 4.
(b) If motor does not run, replace the motor.
(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
WINDSHIELD WIPERS AND WASHERS
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. 5). 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.
