REMOVAL & INSTALLATION



If the wiper assembly has a press type release tab at the center, simply depress the tab and remove the blade. If the blade has no release tab, use a screwdriver to depress the spring at the center. This will release the assembly. To install the assembly, position the blade over the pin at the tip of the arm and press until the spring retainer engages the groove in the pin.

To remove the element, either depress the release button or squeeze the spring type retainer clip at the outer end together, and slide the blade element out. Just slide the new element in until it latches.

Removal of the wiper arms on 1990 vehicles requires the use of a special tool, G.M. J-8966 or its equivalent. Versions of this tool are generally available in auto parts stores. Removal of wiper arms on 1991 - 93 vehicles requires removing the protective cap and mounting nut, then use a battery terminal puller to remove the arm from the knurled shaft.
