THIS BULLETIN REVISES THE PROCEDURE DESCRIBED IN THE 1983 FISHER BODY SERVICE MANUAL (PAGE 2-1) FOR REMOVING, INSTALLING AND ADJUSTING THE WINDSHIELD WIPER BLADE ARMS ON 1982 AND 1983 "J" STYLES. THE FOLLOWING REVISED PROCEDURE SHOULD BE USED WHEN REMOVING, INSTALLING OR ADJUSTING THE WINDSHIELD WIPER BLADE ARMS. REMOVAL AND INSTALLATION: 1. USE TOOL J-8966 OR EQUIVALENT AND LIFT THE ARM OFF THE TRANSMISSION SPINDLE SHAFT (FIG. 2-1). 2. TO INSTALL THE ARM(S), REVERSE THE REMOVAL PROCEDURES AND CHECK THE OPERATION OF THE WIPERS. THE TOOL USED TO REMOVE THE WIPER ARM(S) CAN ALSO BE USED TO INSTALL THE WIPER ARM(S). THE WIPER BLADES ARE TO BE INSTALLED (FIG. 2-2) AS NEAR AS POSSIBLE TO THE TOP EDGE OF THE BLACKOUT LINE ON THE GLASS WITH THE MOTOR IN PARK POSITION. INSPECTION: THE CORRECT BLADE OUT-WIPE POSITION IS 28 MM (1-3/32") FROM THE TIP OF THE BLADE TO THE LEFT WINDSHIELD PILLAR MOULDING (DRIVER'S SIDE) PLUS 17 MM (3/4") OR MINUS 13 MM (1/2"). THIS CHECKING PROCEDURE SHOULD BE DONE ON A WET GLASS SURFACE. ADJUSTMENTS: TO ADJUST THE WIPER ARM TO THE CORRECT BLADE POSITION, REMOVE THE ARM(S) FROM THE SERRATED TRANSMISSION SPINDLE SHAFT. ROTATE THE ARM(S), AS REQUIRED, AND REINSTALL TO THE TRANSMISSION SPINDLE SHAFT. REINSPECT TO INSURE PROPER BLADE OUT-WIPE POSITION.
General Motors bulletins are intended for use by professional technicians, not a "do-it-yourselfer". They are written to inform those technicians of conditions that may occur on some vehicles, or to provide information that could assist in the proper service of a vehicle. Properly trained technicians have the equipment, tools, safety instructions and know-how to do a job properly and safely. If a condition is described, do not assume that the bulletin applies to your vehicle, or that your vehicle will have that condition. See a General Motors dealer servicing your brand of General Motors vehicle for information on whether your vehicle may benefit from the information.
