1986-89 RIVIERAS AND REATTAS
This bulletin has been revised to change bulletin number from 89-8-5 to 89-8-15.
Some 1986-1989 Rivieras and Reattas may experience flickering or blank instrument panel cluster (IPC) and Graphic Control Center (GCC) displays accompanied by code E047. This may be caused by a poor solder connection in the Central Power Supply (CPS). If both the IPC and the GCC displays are flickering or are blank, check the part number on the CPS. If it is 16058596, replace it with Part Number 16088406.
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.
