CHOKE LIGHT REMAINS ON REPLACE CHOKE HEATER RELAY

Conditions may arise where the choke light stays on for some period of time after the engine is started. Engines affected are:

1982 1983

Celebrity LE2, LW9 & LR8 With UF7 LE3 & LW9 Camaro LC1, LG4 & LQ8 LCl, LG4 & LQ8 Cavalier All Canada MN4 Citation LE2 With U22, LH7 With LE2 With U22 U21 & LW9 LH7 With U21 & LW9

Other than the causes indicated in the service manuals for the light staying on, this condition can be the result of a choke heater relay that has too low of a drop out voltage causing the relay to stay energized and the light to stay on. Replacement of the relay with the service part will correct the 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.
