The Air Conditioning System Check on page 8A-62-2 has some incomplete/incorrect information.

The note following DEF in Step 6 of the AIR CONDITIONING: SYSTEM CHECK on page 8A-62-2 should not appear in this step. A note should follow Step 15 reading "R DEFOG and DEFOG cannot be activated using steering wheel controls'.

Please mark-up your copies of the 1991 Eighty-Eight Service Manual accordingly.

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.
