VACUUM LINES FROM THE HEATER AND A/C CONTROL ASSEMBLY TO ACTUATORS WERE LABELED WITH INCORRECT COLORS.

Vacuum line colors shown on page 377 of the Electrical Systems Manual have been revised. The vacuum line from Pin 1 of the Heater and A/C Control Assembly to the Defrost-A/C Valve Vacuum Actuator is blue. The vacuum line from Pin 4 of the Heater and A/C Control Assembly to the Mode Valve Vacuum Actuator is yellow. Please update your 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.
