# OPERA LAMPS INOPERATIVE WIRE MAY BE MISROUTED

#### MODELS AFFECTED: 1986-87 DE VILLES AND FLEETWOODS WITH FORMAL CABRIOLET OR CAMBRIA ROOF OPTIONS

Some 1986 and early production 1987 De Villes and Fleetwoods equipped with a cambria (Option C27) roof and 1986 models equipped with a formal cabriolet (option C10) roof may experience inoperative opera lamps due to incorrect rear cross car harness installation. If the opera lamps are not connected to the harness, first attempt to locate a misrouted opera lamp harness pigtail in the sail panel or under the seat. If a misrouted pigtail is found, reposition it into the sail panel. Reference pages 10C-19 and 10C-20 of the 1986 Body Service Manual for the correct routing of the opera lamp pigtail. If the rear cross car harness does not have a pigtail for the opera lamp, replace the harness using the appropriate part listed below.

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.
