The front and rear wipers and washers are operated by a
switch in the right side control lever. Turn the end of the
control lever to select “Lo,” “Hi,” or one of the five speed
sensitive intermittent windshield wiper speeds. Refer to
“Speed Sensitive Intermittent Wiper System” in this
section. For information on the rear wiper and washer,
refer to “Rear Window Features” in this section. (See
page 164 for more information.)
NOTE:Always remove any build-up of snow that
prevents the windshield wiper blades from returning to
the OFF position. If the windshield wiper switch is
turned off and the blades cannot return to the OFF
position, damage to the wiper motor may occur.

Body Lubrication
Locks and all body pivot points, including such items as
seat tracks, doors, tailgate and hood hinges, should be
lubricated periodically to assure quiet, easy operation
and to protect against rust and wear. Prior to the appli-
cation of any lubricant, the parts concerned should be
wiped clean to remove dust and grit; after lubricating
excess oil and grease should be removed. Particular
attention should also be given to hood latching compo-
nents to insure proper function. When performing other
underhood services, the hood latch, release mechanism
and safety catch should be cleaned and lubricated.
The external lock cylinders should be lubricated twice a
year, preferably in the fall and spring. Apply a small
amount of a high quality lubricant such as MoparLock
Cylinder Lubricant directly into the lock cylinder.
Windshield Wiper Blades
The rubber edges of the wiper blades and the windshield
should be cleaned periodically with a sponge or soft cloth
and a mild nonabrasive cleaner to remove accumulations
of salt or road film.
Operation of the wipers on dry glass for long periods
may cause deterioration of the wiper blades. Always use
washer fluid when using the wipers to remove salt or dirt
from a dry windshield.
Avoid using the wiper blades to wipe frost or ice from the
windshield. Keep the blade rubber out of contact with
petroleum products such as engine oil, gasoline, etc.
Windshield Washers — Front and Rear
On vehicles equipped with a Vehicle Information Center,
the low washer fluid level will be indicated. When the
sensor detects a low fluid level, the windshield will light
on the vehicle graphic outline and the “Washer Fluid
Low” message will be displayed.
