SERV MANUAL UPDATE-SEC.1C ELEC. CLIMATE CONTROL/DIAG

SUBJECT: SERVICE MANUAL UPDATE/SECTION 1C/ELECTRONIC CLIMATE/CONTROL/ DIAGNOSIS (REVISED BLOWER SPEED CHART)

VEHICLES AFFECTED: 1990 "C" MODELS

The "IMPROVED BLOWER SPEED" chart found on page 1C-14 of the Electronic Climate Control sections has been revised.

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.
