General Motors Models
With G.M. models, it is necessary to remove lock and solenoid as an assembly. Remove front seat back panel and seat back trim. Remove front seat back assembly from seat cushion. Remove seat back outer side panel and side panel lower support, where present. Remove manual override handle and escutcheon. Remove hog rings securing seat back front and rear trim facings, and foam pad facing along bottom of seat back. Turn up trim and pull out foam pad to gain access to lock attaching bolts. Disconnect feed connector from lock solenoid. Remove seat back lock attaching bolts and remove lock assembly from seat back with solenoid. To install, engage solenoid plunger bar-to-lock link, then loosely install solenoid and support to seat frame. With lock bolt fully down and solenoid plunger fully extended, adjust solenoid up or down until lock link rivet just contacts bottom of slot in plunger. Tighten solenoid attaching screws. Drill a new 9/64" lock screw hole through solenoid support and seat back frame hinge arm, then install new self tapping lock screw.
