GENERAL INFORMATION
INTRODUCTION
Windshield and rear liftgate glass wiper and
washer systems are standard factory-installed equip-
ment on this model. Refer to 8W-53 - Wipers in
Group 8W - Wiring Diagrams for complete circuit
descriptions and diagrams.
WINDSHIELD WIPER SYSTEM
An intermittent windshield wiper system is stan-
dard equipment on this model. The intermittent
wiper system lets the driver select from either of two
wiper speeds, low or high, or the intermittent wipe
delay mode. A knob on the end of the multi-function
switch stalk is rotated to select the desired wiper
speed, or the intermittent wipe delay mode and inter-
val.
On models equipped with a base version of the
Central Timer Module (CTM), the intermittent wipe
mode delay times are driver adjustable from about
one-half second to about eighteen seconds. On models
equipped with a high-line version of the CTM, the
intermittent wipe mode delay times are speed sensi-
tive. Above about sixteen kilometers-per-hour (ten
miles-per-hour) the delay is driver adjustable from
about one-half second to about eighteen seconds.
Below about sixteen kilometers-per-hour (ten miles-
per-hour) the high-line CTM doubles the delay time,
or provides delays of about one second to about thir-

ty-six seconds. The intermittent wipe mode is pro-
vided by delay logic and relay control circuitry
contained within the CTM, and an intermittent wipe
relay.
The windshield wipers will operate only when the
ignition switch is in the Accessory or On positions. A
fuse located in the junction block protects the cir-
cuitry of the windshield wiper system.
Following are general descriptions of the major
components in the windshield wiper system. Refer to
the owner's manual in the vehicle glove box for more
information on the features, use and operation of the
windshield wiper system.
WINDSHIELD WASHER SYSTEM
An electrically operated windshield washer system
is standard equipment. A knob on the end of the
multi-function switch stalk is depressed toward the
steering column to activate the washer system. A
washer reservoir in the engine compartment holds
the washer fluid, which is pressurized by a pump
when the windshield washer switch is actuated. The
windshield washer pump feeds the pressurized
washer fluid through the washer system plumbing to
the windshield washer nozzles.
A standard equipment low washer fluid warning
lamp in the instrument cluster will warn the driver
when the washer fluid level needs to be checked.
Refer to Group 8E - Instrument Panel Systems for
more information on this feature.
