(3) Secure arm to pivot with attaching nut and
tighten 17 to 22 N Im (155 to 195 in. lbs.) torque.
(4) Close head cover and remove pin from arm pin
hole.
WIPER ARM ADJUSTMENT
FRONT ARM ADJUSTMENT
(1) Cycle the wiper motor into the PARK position.
(2) Check the tips of the blades in blackout area.
From the bottom edge of the windshield to the blade
should be no closer than 25 mm (1 inch) (Fig. 8). (3) Operate the wipers if the requirements are not
met, check linkage and pivot assembly for worn
parts.
REAR ARM ADJUSTMENT
With the motor in the park position, mount the
arm on the motor shaft. Choose a serration engage-
ment that positions the blade, parallel with the bot-
tom edge of the liftgate glass.

WIPER MOTOR SYSTEM TEST PROCEDURES
WARNING: ON VEHICLES EQUIPPED WITH AIR-
BAG, SEE GROUP 8M, RESTRAINT SYSTEMS FOR
STEERING WHEEL OR COLUMN REMOVAL PROCE-
DURES.
Whenever a wiper motor malfunction occurs, first
verify that the wiper motor wire harness is properly
connected to all connectors before starting normal di-
agnosis and repair procedures. Refer to Wiper Motor
Diagnosis Chart (Fig. 9). 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. These tests will cover both two speed and in-
termittent wipe functions.
TWO SPEED MOTOR FUNCTION TESTS
CONDITION: MOTOR WILL NOT RUN IN ANY SWITCH POSITION
PROCEDURE
(1) Check for a blown fuse in the fuse block. (a) If fuse is good, proceed 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, proceed to step 2. (d) If replacement fuse blows, proceed to step 5.
(2) Place switch in LOW speed position.
(3) Listen to motor. If you cannot hear it running,
proceed to Step 4. If you hear it running, check motor
output shaft. If output shaft is not turning, replace
motor assembly. If it is turning, drive link to output
shaft or linkage is not properly connected. Replace
worn parts and/or properly connect drive link to the
motor output shaft. (4) Connect a voltmeter between motor terminal 3
and ground strap (Fig. 10). If there is no voltage or very
little voltage (less than one volt) present, move nega-
tive test lead from the ground strap to negative battery
terminal. (a) If an increase in voltage is noticed, the problem
is a bad ground circuit. Make sure the motor mount-
ing is free of paint and that nuts or bolts are tight. (b) If there is still no indication of voltage, the
problem is an open circuit in the wiring harness or
wiper switch. (c) If no more than 3 volts increase in voltage is
observed, the problem is a faulty motor assembly.
(5) Disconnect motor wiring connector and replace
fuse. (a) If fuse does not blow, motor is defective.
(b) If fuse blows, switch or wiring is at fault.
