motion while the arm is in an over/centered position
(Fig. 6).
(6) Remove the cowl cover. The right side cover
overlaps the left side cover, so they both must be
removed.
(a) Remove the rear engine compartment seal at
the cowl.
(b) Remove the four push retainers to the right
side cowl cover and remove from vehicle.
(c) Remove the three push retainers to the left
side cowl cover and remove from vehicle.

(10) Remove three bolts to the front wiper motor
and separate from module.
INSTALLATION
(1) Place the motor on the wiper linkage and
install the three bolts to the front wiper motor.
(2) Reconnect the drive link to the motor crank
ball joint.
(3) Place the front wiper module into cowl area
and install the three mounting bolts (Fig. 12). Torque
the mounting screws to 8 N·m (75 in. lbs.).
(4) Connect the front wiper motor posi-lock har-
ness connector.
(5) Install the cowl cover. The right side cover
overlaps the left side cover.
(a) Place the left side cowl cover into position
and install the three push retainers.
(b) Place the right side cowl cover into position
and install the four push retainers.
(c) Install the rear engine compartment seal at
the cowl.
Before installation of the front wiper arms, activate
the wiper system to ensure the front wiper module is
in the PARK position. Position wiper arms so that
the tip of the driver’s blade and the middle of the
passenger’s blade is on the park line on the wind-
shield (Refer to 8 - ELECTRICAL/WIPERS/WASH-
ERS/WIPER ARMS - ADJUSTMENTS).
(6) Place the arm on the pivot while the arm is in
an over/centered position (Fig. 6).
(7) Install the wiper arm retaining nut (Fig. 6) and
torque to 21 N·m (190 in. lbs.).
(8) Install the wiper arm nut cap (Fig. 6).
(9) Connect the battery negative cable (Fig. 11).
(10) Close hood.
(11) Verify vehicle and system operation.
