CAMPAIGN: PASSENGER SIDE SEAT EASY-ENTRY ADJ. FAILS TO LOCK
Subject: PASSENGER'S SIDE EASY-ENTRY SEAT ADJUSTER - FAILS TO LOCK IN POSITION
Models: Certain 1992 Buick Skylark, Skylark GS and Pontiac Grand Am Coupe Models Equipped with Easy-Entry Seat
General Motors of Canada Limited has determined that a defect which relates to motor vehicle safety exists in certain 1992 Buick Skylark, Skylark GS and Pontiac Grand Am Coupe models. These vehicles may exhibit a condition in which the passenger's side Easy-Entry seat adjuster may fail to fully lock into position after the seat back has been tilted forward and the seat slid forward and then back to its original position to allow entry or exit to or from the rear seat area.
If the seat is not fully locked in position, the entire seat assembly could slide forward during a rapid deceleration. If this were to occur while the passenger seat was occupied, the resultant forward travel of the seat could result in serious injury to the occupant.
To prevent this condition from occurring, dealers are to replace the passenger's side Easy-Entry seat adjuster mechanism on all vehicles involved in this campaign.

15. Examine old adjuster mechanism and note position of large assist spring. Remove large assist spring from old adjuster assembly and reinstall on new adjuster assembly as follows:
A. Hook long-shank end of spring into rear-most large hole on upper channel of RH, or outboard side. This hole is approximately 3/4" in diameter and is just forward of the bolt hole for the RH rear bolt that attaches the adjuster assembly to the seat frame.
B. Hook the short-shank end of the assist spring into the slotted hole located on the side of the LH, or inner front floor mounting support or "foot."
16. Remove the four (4) bolts that attach the old adjuster assembly to the seat frame. Remove old adjuster assembly.

19. Unlatch the fore/aft lock mechanism using the fore/aft adjustment handle and slide the adjuster to the full-forward position (lower channels and adjuster mounting "feet" are fully rearward). Visually inspect the locking mechanism to make sure that the adjuster is locked in the full-forward 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.
