In the event of an electrical failure of a 6-way power seat AG1 and AG2 option on the above vehicles, check to see if the wiring connector had pulled away from the back of the switch. If it has, this can be caused by tension on the seat jumper wire due to wire routing in assembly.
CORRECTION
1. Secure 6-way power seat harness just after power feed wires break out from tape wrapping to outboard spring on cushion frame with one (1) strap (11509088 or equivalent). Trim off excess strap approximately 25.4mm beyond joint. See View A.
2. Remove seat switch and disconnect. Bend (by hand only) seat jumper wires at switch connector 180 deg.; Sketch B. Reinstall switch.
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.
