Cherokee 2WD L6-4.0L VIN S (1998)
Wiper Arm: Description and Operation
SYSTEM OPERATION
All Cherokee models have two 45.72-centimeter (18-inch) windshield wiper blades with non-replaceable rubber elements (squeegees). The
optional rear wiper uses a single 33.0-centimeter (13-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 entire wiper blade assembly 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 wiper blades 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 directly to the rear wiper motor output shaft on the liftgate below the liftgate glass.
The wiper arms and blades cannot be adjusted or repaired. If faulty or damaged, they must be replaced.
