COOLANT FAN - V6 EXCEPT AIR CONDITIONING
Dear Buick Owner:
General Motors has determined that some 1983 Buick Centurys were assembled with an engine cooling fan relay that may fail. A failed relay can cause
the fan motor to continue to operate with the ignition switch in the "OFF" position, resulting in a discharged battery.
