RELAY CIRCUIT TEST
(1) The relay common feed terminal cavity (30) is
connected to the wiper (multi-function) switch. There
should be continuity between the cavity for relay ter-
minal 30 and the two fused ignition switch output
circuit cavities of the multi-function switch wire har-
ness connector at all times. If OK, go to Step 2. If not
OK, repair the open circuit(s) to the multi-function
switch as required.
(2) The relay normally closed terminal (87A) is
connected to terminal 30 in the de-energized position.
There should be continuity between the cavity for
relay terminal 87A and the wiper park switch sense
circuit cavities of the wiper motor wire harness con-
nector and the 14-way Central Timer Module (CTM)
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 CTM 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
CTM 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 14-way CTM wire harness
connector. There should be continuity. If OK, replace
the faulty base version CTM; or, use a DRB scan tool

and the proper Diagnostic Procedures manual for

repair the open circuit to the CTM as required.
REMOVAL AND INSTALLATION
WIPER BLADE
FRONT
NOTE: The driver side and passenger side wiper
blades are not interchangeable. The driver side
wiper blade has an extra bridge and eight pairs of
claws securing the wiper element. The passenger
side wiper blade has six pairs of claws securing the
wiper element. The notched retainer end of both
wiper elements should always be oriented towards
the end of the wiper blade that is nearest to the
wiper pivot.
(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) 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. 5).

(4) To install the wiper blade on the wiper arm,
slide the blade retainer into the U-shaped formation
on the tip of the wiper arm until the release tab
snaps into its locked position. Be certain that the
notched retainer for the wiper element is oriented
towards the end of the wiper blade that is nearest to
the wiper pivot.
