GM Cutlass RWD 1970-1987 Repair Guide

Blade and Arm


See Figures 1, 2 and 3


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 requires the use of a special tool, G.M. J-8966 or its equivalent. Versions of this tool are may be available in auto parts stores.

  1. Insert the tool under the wiper arm and lever the arm off the shaft.

Raising the hood on most later models will facilitate easier wiper arm removal.
