SUBJECT: AIR CONDITIONING NOISE/VIBRATION
MODELS: 1987-88 S/T TRUCKS WITH 2.8L ENGINE AND AIR CONDITIONING
Some 1987-88 S/T Trucks equipped with 2.8L engines may exhibit a noise/vibration when the air conditioning compressor is engaged. The noise/vibration is the result of a resonance set up in the serpentine accessory drive system with air conditioning on. If this condition is experienced, install A/C compressor brace kit P/N 10115893. Installation instructions are included with the kits.
Parts are expected to be available on 9/15/88. Until then, normal part orders will not be accepted by GMSPO. Only verifiable emergency VIP orders will be accepted. SPO will make every effort to obtain parts. All parts will be placed on 400 control to waive VIP surcharges. However, the part will be shipped premium transportation at dealer's expense. All other order types will be canceled as incorrectly ordered while the 400 control is in place.
