FUSE 15 WIPER
8K - 2 WINDSHIELD WIPERS AND WASHERS
DESCRIPTION AND OPERATION (Continued)
remove the accumulation of salt and road film. The
wiper blades, arms, and windshield should be
cleaned with a sponge or cloth and a mild detergent
or nonabrasive cleaner. If the blades continue to
streak or smear, they should be replaced. The right
and left wipers are different blade lengths. The
driver side length is 525 mm and the passenger side
length is 450 mm. The blades should not be inter-
changed.

DIAGNOSIS AND TESTING

WINDSHIELD WIPER CONDITION

WARNING: ON VEHICLES EQUIPPED WITH AIR-
BAGS, SEE GROUP 8M, RESTRAINT SYSTEMS FOR
STEERING WHEEL OR COLUMN REMOVAL PROCE-
DURES.
The following is a list of general wiper motor sys-
tem problems, the tests that are to be performed to
locate the faulty part, and the corrective action to be
taken.
Whatever the problem, disconnect motor wire har-
ness and clean the terminals, then connect motor
wire harness and test.
MOTOR WILL NOT OPERATE IN SOME OR ALL
SWITCH POSITIONS
(1) Check fuse 15, in the fuse block (Fig. 1).
(a) If fuse is OK, go to Step 2.
(b) If fuse is defective, replace and check motor
operation in all switch positions.
(c) If motor is still inoperative and the fuse does
not blow, go to Step 2.
(d) If replacement fuse blows, go to Step 6.

(2) Disconnect motor wire connector.
(3) Check motor low speed. Using two jumper
wires, connect one jumper wire between the battery

positive terminal and terminal 2 of the motor connec-
tor. Connect the other jumper wire to the battery
negative terminal and the motor ground strap (Fig.
2). Check motor high speed, connect the positive
jumper wire to terminal 1 of the motor connector.
Connect the negative jumper wire to the motor
ground strap.
(a) If motor does not run, high or low speed go to
Step 4.
(b) If motor runs, go to Step 5.

(4) Using an ohmmeter, check for good ground at
the motor ground strap. If OK, replace motor. If not
repair the ground circuit as necessary.
(5) Check terminal E of wiper switch connector for
continuity to ground. If OK, go to Step 6. If not OK,
repair the ground circuit as necessary.
(6) Using a voltmeter, with wiper switch con-
nected, connect negative lead to motor ground strap.
Connect the positive lead to terminal P1 of the wiper
switch connector (Fig. 3) and (Fig. 5).
(a) If no voltage, repair wiring as necessary. If
OK, go to Step 2.
(b) Check wiper switch low speed, connect volt-
meter positive lead to terminal L of the wiper
switch connector. Move wiper stalk to LOW posi-
tion. If no voltage, replace switch.
(c) Check wiper switch high speed, connect volt-
meter positive lead to terminal H of the wiper
switch connector. Move wiper stalk to HIGH posi-
tion. If no voltage, replace switch.
(7) Disconnect motor connector and replace fuse 15
in fuse block.
(a) If fuse does not blow, replace motor.
(b) If fuse blows, disconnect wiper switch and
replace fuse.
(c) If fuse does not blow, replace switch.
(d) If fuse blows, repair wiring as necessary.
MOTOR OPERATES SLOWLY AT ALL SPEEDS
(1) Remove wiper arms and cowl screen. Discon-
nect motor linkage from motor. Connect an ammeter
between battery positive terminal and terminal 4 of
