Some 1989 Cadillac models may exhibit a condition of poor AM or FM radio reception. This may be caused by a poor contact on the female terminal of the antenna coaxial cable lead.
Figure 1 shows a four-step procedure to test and repair the female terminal. The opening in the female terminal should range from .120" to .125" in diameter. A .125" pin gage should have some resistance to passing through the female terminal. If the gage passes through freely, the terminal should be repaired as illustrated. Gage sets are available from Kent-Moore using tool number J-26900-14.
For warranty purposes use Labor Operation T6369 at .5 hour for all carlines.
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.
