Some comments have been received that the background of the "Cruise" warning lamp glows when the cruise control is not engaged. This is a normal condition for this cluster. The word "Cruise" will come on whenever the cruise control is engaged, and will not appear when the cruise control is "off".
No repair should be attempted for this normal condition.
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.
