Some vehicles may experience a high pitched whine or buzzing noise that originates from the speedometer when the vehicle is in motion. A sound
deadening rubber gasket has been added between the speedometer drive motor and the back of the speedometer assembly to eliminate noise in new
speedometers. Dealers may either order the assembly from GMSPO for replacement in-house or send the I.P. cluster to their Delco Service Center for
repair. For in-house repair, the new speedometer assembly part numbers are 16131595 for early production vehicles and 16128247 for later production
vehicles with red indicator on speedometer dial.
Parts are expeded to be available on February 27, 1989. 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.
