Service Manual Section 8A, 1989 Oldsmobile Cutlass Supreme pages 130-2 and 130-4. On page 130-2 delete Troubleshooting Hint #4.
On page 130-4 delete paragraph 4 which reads:
"The LH Door Lock Switch is illuminated with an LED with the light switch in HEAD or PARK. The Driver's door lock switch also has a time delay illumination function that lights the switch for 45 seconds after the lights have been turned off."
Replace the deleted paragraph with the following:
"The Unlock Indicator is an LED which lights to indicate that the LH door is unlocked. The LED will light whenever the ignition is in RUN and LH door switch is closed."
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.
