2004 Buick Rendezvous Wiper Blade

You need to turn the ignition switch to the ACCY position, turn the wiper switch to the DELAY position, then turn the ignition OFF, push in the button of the wiper blade clip, remove the wiper blade from the inside radius of the wiper arm, and bring the wiper arm out through the opening in the wiper blade.

The proper way is to insert the open end of the wiper blade element into the bottom claws of the wiper blade, guide the wiper blade element through the wiper blade claw sets, engage the bottom claw of the wiper blade into the notches in the wiper blade element and install the wiper blade onto the wiper arm.

You need to remove the rear wiper blade from the rear wiper arm, remove the rubber wiper element from the element vertebra, then remove the element vertebra and end cap from the rear wiper blade.

You need to remove the wiper blades from the wiper arms, then look down the length of the blade element, replace the wiper blade element if the rubber element which contacts the glass is not on the centerline of the blade +/-15 degrees, then install the wiper blades on the wiper arms.
