BLADE, Wiper

FRONT

FRONT

Each front wiper blade is secured by an integral latching pivot block (3) to the hook formation on the tip of each wiper arm, and rests on the glass near the base of the windshield when the wipers are not in operation. The wiper blade consists of the following components:

• Superstructure (1) - The superstructure includes several stamped steel bridges and links with claw formations that grip the wiper blade element. Also included in this unit is the latching, molded plastic pivot block that secures the superstructure to the wiper arm. All of the metal components of the wiper blade have a satin black finish applied.
• Element (2) - The wiper element or squeegee is the resilient rubber member of the wiper blade that contacts the glass.
• Flexor (7) - The flexor is a rigid metal component running along the length of each side of the wiper element where it is gripped by the claws (6) of the superstructure.

All vehicles have interchangeable windshield wiper blades with non-replaceable rubber elements (squeegees). The blades are 37.50 centimeters (14.76 inches) long. The wiper blades cannot be adjusted or repaired and, if ineffective, worn, or damaged, the entire wiper blade unit must be replaced.

REAR

The rear wiper blade is secured by an integral pivot pin (4) to the latch formations on the underside of the tip of the rear wiper arm, and rests near the top of the lift glass when the rear wiper system is not in operation. The rear wiper blade consists of the following components:

• Superstructure (3) - The superstructure includes a molded black plastic bridge and plastic links with claw formations that grip the wiper blade element. Also included in this unit is the molded plastic pivot pin that secures the superstructure to the wiper arm.
• Element (1) - The wiper element or squeegee is the resilient rubber member of the wiper blade that contacts the glass.
• Flexor (2) - The flexor is a rigid metal component running along the length of each side of the wiper element where it is gripped by the claws of the superstructure.

The rear wiper blade is 27.90 centimeters (10.98 inches) long with a replaceable element (squeegee). The wiper blade superstructure cannot be adjusted or repaired. If ineffective, worn or damaged the entire wiper blade unit must be replaced.

The wiper blades are moved back and forth across the glass by the wiper arms when the wipers are being operated. The wiper blade superstructure is the flexible frame that grips the wiper blade element and evenly distributes the force of the spring-loaded wiper arm along the length of the element. The combination of the wiper arm force and the flexibility of the superstructure makes the element conform to and maintain proper contact with the glass, even as the blade is moved over the varied curvature that may be encountered across the glass surface.

The wiper element flexor provides the claws of the blade superstructure with a rigid, yet flexible component on the element which can be gripped. The rubber element is designed to be stiff enough to maintain an even cleaning edge as it is drawn across the glass, yet resilient enough to conform to the glass surface and flip from one cleaning edge to the other each time the wiper blade changes directions.

STANDARD PROCEDURE - REAR WIPER ELEMENT REPLACEMENT

STANDARD PROCEDURE - REAR WIPER ELEMENT REPLACEMENT

1. Remove the rear wiper blade (3) from the wiper arm. (Refer to 08 - Electrical/8R - Wipers/Washers/BLADE, Wiper - Removal) .

 
2. Grasp one of the wiper blade links (4) firmly with one hand, and grasp the wiper element (1) and flexors (2) midway between the two links with the other hand.

 
3. Pull the element and flexor away from the blade far enough to disengage them from the end pair of claws (5) of one link.

 
4. Slide the element and flexor toward the loose end to disengage them from the remaining sets of claws.

 
5. Reverse this process to install a new element and flexors into the wiper blade.

 
6. Reinstall the wiper blade onto the wiper arm. (Refer to 08 - Electrical/8R - Wipers/Washers/BLADE, Wiper - Installation) .

1. Lift the wiper arm (2) to raise the wiper blade and element (6) off of the glass, until the wiper arm hinge is in its over-center position.

 
2. To remove the blade from the arm, depress the latch release tab (4) on the pivot block (3) under the tip of the arm and slide the blade away from the tip towards the pivot end of the arm far enough to disengage the pivot block from the hook formation (5) on the end of the arm.

 
3. Extract the hook formation on the tip of the wiper arm through the opening in the wiper blade superstructure (1) just ahead of the pivot block.

 
4. Gently lower the tip of the wiper arm onto the glass.

1. Lift the wiper arm (2) to raise the wiper blade and element (1) off of the glass.

 
2. To remove the blade from the arm, swing the end of the wiper blade nearest to the wiper motor away from the wiper arm to its travel limit.

 
3. Now press the end of the wiper blade nearest to the wiper motor away from the wiper arm against its stop far enough to unsnap the wiper blade pivot pin from the latch features on the underside of the wiper arm.

 
4. Gently lower the tip of the wiper arm onto the glass.

1. Lift the wiper arm (2) off of the windshield glass, until the wiper arm hinge is in its over-center position.

 
2. Position the wiper blade near the hook formation (5) on the tip of the arm with the notched end of the wiper element flexor oriented towards the end of the wiper arm that is nearest to the wiper pivot.

 
3. Insert the hook formation on the tip of the arm through the opening in the blade superstructure (1) ahead of the pivot block (3) far enough to engage the pivot block into the hook.

 
4. Slide the pivot block up into the hook formation on the tip of the wiper arm until the latch release tab (4) snaps into its locked position. Latch engagement will be accompanied by an audible click.

 
5. Gently lower the wiper blade and element (6) onto the glass.

1. Lift the wiper arm (2) off of the lift glass.

 
2. Position the wiper blade (1) under the tip of the wiper arm, aligning the pivot pin near the center of the blade superstructure with the latch features on the underside of the tip of the arm.

 
3. Squeeze the arm and blade together until the blade pivot pin snaps into the latch features of the arm.

 
4. Gently lower the wiper blade and element onto the glass.
