SIX WAY SEAT AND WINDOW SWITCH REMOVAL

VEHICLES AFFECTED: 1985 'C' Styles

If one of the subject switches requires replacement make certain that the power feed circuit is not shorted to any other wire in the circuit before installing a new switch. If this procedure is not followed and a short exists, the short will cause the replacement switch points to burn.

In addition, when disconnecting the seat switch from the wiring harness, extra care must be taken not to short across the switch hot feed terminal and a switch ground terminal. If above condition occurs, the seat switch can be damaged.

Also, when disconnecting a window switch, the ignition switch must be in the off position. This procedure will eliminate the possibility of shorting out the window switch if a screwdriver or awl is used to remove the switch from the harness.

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.
