REMOVAL & INSTALLATION
See Figures 1, 2, 3, 4, 5 and 6
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 suitable tool to depress the spring at the center of the blade. This will release the entire assembly from the wiper arm. 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 retainer clip at the outer end of the blade and slide the element off. On installation, simply slide the new element in until it latches onto the blade.
Removal of the wiper arms on all models but the 1986 Eldorado and Seville requires the use of a special tool, G.M. J8966, or its equivalent. Versions of this tool are available in most auto parts stores. On the 1986 Eldorado and Seville, raise the arm, insert a suitable pin into the hole at the base of the arm until the spring tension is released and then remove the arm.
- Insert the special tool under the base of the wiper arm and lever the arm off the linkage shaft.
On most later models, raising the hood will facilitate wiper arm removal.
- Disconnect the washer hose from the arm (if so equipped). Remove the wiper arm.
- Installation is in the reverse order of removal. The proper park position (when arms are at rest) is for the blades to be approximately 2 in. (50mm) above the lower molding of the windshield. Be sure that the wiper motor is in the park position before installing the arms.
