Cadillac 84574892 Blade Assembly, Wsw

Windshield wiper and blade assembly must be checked on a regular basis for the signs of damage, such as worn out parts, a losable wiper arm or frame, and cracks or wear on the blade elements. Road film can accumulate on the wiper blades and reduce their performance and therefore the blades should be washed frequently especially using a solution of mild detergent. If, for instance, the wiper blade elements are either cracked, worn or even warped or cannot clean sufficiently anymore, then they have to be regenerated through new wiper blade elements. To replace the wiper blade assembly, one has to pull up on the arm assembly to create enough room from the glass, a tab has to be opened and the wiper blade assembly has to be slid downward along the arm until the pivot is no longer in the hook that is at the end of the arm and then the blade assembly can be removed. Secure the new wiper to the arm ensuring it locks into place by producing a clicking sound, with further securing done by pressing the release tab downwards.

The wiper blade elements should be replaced if they are cracked, worn, warped, or no longer clean adequately.
