Start by placing the Ignition Switch at accy and turning the Wiper Switch to delay mode or auto delay. Turn off the ignition when the wiper arms remain fixed on the inner wipe position. Remove the washer hose from the washer connector then place your marker or tape on the Wiper Blade position before you begin service. Lift up the hood to get to the nut underneath its protective cover before taking out the nut. When the Wiper Arm remains fixed to the Drive Shaft you should use the Wiper Arm puller (part number J 39822) to disconnect it. Scrub the Drive Shaft knurls with a wire brush before taking off the Wiper Blade assembly if needed. Install the Wiper Blade first then position the Wiper Arm back where the mark shows during removal operation. You must enable the Wiper Arm to move during handwritten to achieve a torque setting of 25 n.m (18 lb ft) while holding the Wiper Arm. Add windshield washer solvent to the washer hose for smooth installation onto its connector and close the hood afterward.

  Q: How to replace the wiper arm on Buick Park Avenue?

  A:

  You need to power on accy from the Ignition Switch and set the Wiper Switch to delay or auto delay before workshop work begins. Disconnect the washer hose from the connector when the wiper arms sit still at their inner wiping position and you can shut the ignition. Use a permanent marker or tape to show where the Wiper Blade touches the windshield and lift the hood. Take off the nut shield first, then unscrew the nut and Wiper Arm from the same shaft as the drive. When rocking fails to release the Wiper Arm you must use the Wiper Arm puller tool (J 39822). Scrub the Drive Shaft knurling with wire brush before taking off the Wiper Blade from the arm when needed. Before adding the Wiper Arm place the Wiper Blade onto the Drive Shaft alignment. Put the Wiper Arm on the transmission Drive Shaft following the mark made earlier. Put the transmission Drive Shaft nut in place while letting the Wiper Arm move sometime before you tighten the nut to 25 n.m (18 lb ft). Adjust the Wiper Arm position when the nut is loose and it slides away from the alignment mark. Put the washer hose onto the washer hose connector and add windshield washer solvent as a lubricant for easy installation. Perform multiple tests after installation: close the hood, use a cloth to erase position marks from the windshield, use wipers to see the expected movement, and make sure wipers safely park when switched off.
