BLOWER MOTOR 'TICKING' NOISE (REPLACE BLOWER MOTOR AND FAN)

BLOWER MOTOR "TICKING" NOISE

VEHICLES AFFECTED: 1988 C/K ------------------

A ticking noise due to blower motor vibration may be heard on some 1988 C/K trucks. The ticking noise is noticeable at all blower speeds. Should a customer comment about the noise, it may be eliminated by installing a new blower motor and new fan. The new blower motor has a ribbed base flange that reduces vibration and the new fan is specially designed for operation with the new motor. Parts Information

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.
