(BCM) wire harness connector at all times. If OK, go
to Step 3. If not OK, repair the open circuit(s) to the
wiper motor and BCM as required.
(3) The relay normally open terminal (87) is con-
nected to the common feed terminal (30) in the ener-
gized position. There should be battery voltage at the
cavity for relay terminal 87 with the ignition switch
in the On or Accessory positions. If OK, go to Step 4.
If not OK, repair the open circuit to the ignition
switch as required.
(4) The coil battery terminal (86) is connected to
the electromagnet in the relay. There should be bat-
tery voltage at the cavity for relay terminal 86 with
the ignition switch in the On or Accessory positions.
If OK, go to Step 5. If not OK, repair the open circuit
to the ignition switch as required.
(5) The coil ground terminal (85) is connected to
the electromagnet in the relay. It is grounded by the
BCM to energize the relay and cycle the wiper motor.
Check for continuity between the cavity for relay ter-
minal 85 and the intermittent wiper relay control cir-
cuit cavity of the white 24-way BCM wire harness
connector. There should be continuity. If OK, refer to
the proper Body Diagnostic Procedures manual for
diagnosis of the BCM. If not OK, repair the open cir-
cuit to the BCM as required.
REMOVAL AND INSTALLATION
WIPER BLADE AND ELEMENT
FRONT
NOTE: The pinch-release retainer end of the wiper
element should always be oriented towards the end
of the wiper blade that is nearest to the wiper pivot.
To remove the windshield wiper blade and/or ele-
ment, proceed as follows:
(1) Turn the windshield wiper switch to the On
position. By turning the ignition switch to the On
and Off positions, cycle the wiper blades to a conve-
nient working location on the windshield.
(2) Lift the wiper arm to raise the wiper blade and
element off of the windshield glass.
(3) Remove the wiper blade from the wiper arm, or
the wiper element from the wiper blade as follows:
(a) To remove the wiper blade from the wiper
arm, push the release tab under the arm tip and
slide the blade away from the tip towards the pivot
end of the arm (Fig. 3).
(b) To remove the wiper element from the wiper
blade, pinch the notched retainer (pivot) end of the
wiper element tightly between the thumb and fore-
finger (Fig. 4). Then, pull the element firmly
towards the wiper pivot to release the wiper blade
claws from the wiper element retaining pockets.
Once the claws are released from the retaining
pockets, the element will slide easily out of the
remaining claws.
(4) Install the wiper blade on the wiper arm, or
the wiper element in the wiper blade as follows:
(a) To install the wiper blade on the wiper arm,
slide the blade retainer into the U-shaped forma-
tion on the tip of the wiper arm until the release
tab snaps into its locked position. Be certain that
the pinch-release for the wiper element is oriented
towards the end of the wiper blade that is nearest
to the wiper pivot.
(b) To install the wiper element in the wiper
blade, be certain that the metal element rails (ver-
tebra) are properly seated in the slots on either
side of the rubber element. Start at the wiper pivot
end of the blade and slide the element through
each pair of wiper blade claws. The element is fully
installed when the claws on the wiper pivot end of
the blade are engaged in the wiper element retain-
ing pockets.
REAR
NOTE: The pinch-release retainer end of the wiper
element should always be oriented towards the end
of the wiper blade that is nearest to the rear wiper
motor output shaft.
