Grand Cherokee 2WD V8-5.2L VIN Y (1998)
Wiper Blade: Description and Operation
SYSTEM OPERATION
All Grand Cherokee models have two 50.8-centimeter (20-inch). windshield wiper blades with replaceable rubber elements (squeegees). The rear
wiper uses a single 30.48-centimeter (12-inch) wiper blade with a non-replaceable rubber element (squeegee).
Caution should be exercised to protect the rubber squeegees from any petroleum-based cleaners or contaminants, which will rapidly deteriorate the
rubber. If the squeegees are damaged, worn, or contaminated, the squeegees (front) or the entire wiper blade assembly (rear) must be replaced.
Wiper squeegees exposed to the elements for a long time tend to lose their wiping effectiveness. Periodic cleaning of the squeegees is suggested to
remove deposits of salt and road film. The wiper blades, arms, and windshield or rear glass should be cleaned with a sponge or cloth and
windshield washer fluid, a mild detergent, or a non-abrasive cleaner. If the squeegees continue to streak or smear, the squeegees (front) or wiper
blade (rear) should be replaced.
The blades are mounted to spring-loaded wiper arms. The spring tension of the wiper arms controls the pressure applied to the blades on the glass.
The windshield wiper arms are secured by an integral latch to the two wiper pivots on the cowl plenum cover/grille panel at the base of the
windshield. The rear wiper arm is secured by a nut under the wiper arm pivot-end cover directly to the rear wiper motor output shaft on the liftgate
panel.
