A Jeep's windshield wiper problems may extend beyond the blades. The Jeep's wiper system also includes the wiper's arms, pivots, motor and transmission. If any of those malfunction, the wipers will not work.
A wiper blade is made up of a frame, rubber insert and a center connection point. A worn or frayed blade will not effectively remove water. If the frame is bent, the blade will not have full contact with the windshield. Plus, if the frame's center connection is damaged, it will not be secure on the Jeep's wiper arm.
Wiper arms are also attached to a pivot, which serves as the arm's connection to the wiper's motor and transmission. If the pivot is damaged, the arms will not move properly. If the arm is bent, it will not function correctly. The wiper also contains an internal spring. If this spring is stretched out of shape, the arm will not be secure against the windshield.
The Jeep's wiper motor and transmission is located beneath the hood, in the rear of the engine compartment. Both are responsible for moving the arm and blade back and forth. Any mechanical malfunction will make the movements erratic or non-existent.
The wiper blade system also relays on the Jeep's electrical network. Blown fuses can result in problems and faulty relays can also impact functionality. Damaged wiring could also be to blame.
