# CHOKE RELAY BUZZ REPLACE RELAY WITH NEW P/N

#### MODEL AFFECTED: SOME 1982 THRU 1985 SKYLARKS EQUIPPED WITH 2.8L ENGINE (VIN CODES X OR Z)

Some 1982-1985 Skylarks equipped with a 2.8L engine (VIN Codes X or Z), may exhibit a choke relay "buzz" condition when the ignition key is turned "off" and the A/C and heater controller is in the "off" position (no blower operation). This condition has been thoroughly investigated and found to be the relay rather than the generator.

This "buzz" condition can be eliminated by replacing the old relay, P/N 14039662, with a new relay, P/N 14089568, which has a diode in series with the relay coil.

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.
