During cold weather, the effort required to energize the horn may be higher than some owners desire due to the stiffness of the vinyl material horn pad/cap at low temperatures.
The horn/pad cap was changed in production to a softer vinyl June 12, 1984. To correct owner vehicles, the softer vinyl horn pad/cap is available as a replacement through the normal parts channels.
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.
