Lincoln 4U2Z-17528-FA Wiper Blade Assembly

Raise the blade end of the front wiper arm off of the windshield. Move the slide latch away from the pivot shaft. The wiper-arm can now be removed from the shaft without the use of any tools.

Regardless of the type of refill used, make sure that all of the frame jaws are engaged as the refill is pushed into place and locked. If the metal blade holder and frame are allowed to touch the glass during wiper operation, the glass will be scratched.

Cycle the wiper assembly to a position on the windshield where removal of the blade assembly can be performed without difficulty. Turn the ignition key off. With the blade assembly resting on the windshield, insert a small screwdriver into the release spring at the center of the blade and push down on the spring. While pressing down, pull the wiper blade off the wiper arm pin.

The wiper blades should be washed regularly with a mild detergent solution.

If inspection reveals hardened or cracked rubber, replace the wiper blades.
