SERVICE MANUAL UPDATE SEC. 8A ELECTRICAL DIAGNOSIS (ECC)

SUBJECT: SERVICE MANUAL UPDATE - 8A - L DIAGNOSIS (REVISED) ELECTRONIC AIR CONDITIONING- C68

VEHICLES AFFECTED: 1992 "C AND K" MODELS

This bulletin has been revised to add the 1992 "C" car and to alter the text to explain the correction so the artwork will not have to be republished.

Wire leads connecting the Air Mix Valve Actuator to the HVAC Programmer were improperly identified as having a black insulation color on the "AIR CONDITIONING: AIR DELIVERY AND TEMPERATURE CONTROL" chart on page 8A-68-1 of the 1992 "H" car Service Manual and page 8A-68-4 of the 1992 "C" car Service Manual. The correct insulation color for each of these leads is white. Please note this correction in your copies of the appropriate service manuals.

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.
