The seat belt warning light may remain "on" in 1987 and 1988 Cutlass Calais vehicles equipped with the gage cluster and passive restraints.
This condition occurs due to intermittent contact welding of the seat belt indicator module when used with a 3 Candle Power (CP) bulb in the gage cluster.
To repair the above mentioned condition, replace the seat belt indicator module with part number 22534666 and replace the 3 candle power seat belt indicator bulb in the gage cluster with a 2 candle power bulb, part number 25089350.
Parts are currently available through GMSPO.
Use applicable Labor Operation and Labor Times.
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.
