SUBJECT:
INTERMITTENT DEAD BATTERY OR COOLING FANS REMAINING ON AFTER IGNITION OFF

MODELS AFFECTED:
1988-1990 DE VILLES AND FLEETWOODS

This bulletin supersedes Service bulletin T-90-19, dated 11/89 which should be discarded.

Some 1988-1990 DeVilles and Fleetwoods may experience an intermittent dead battery or cooling fans remaining on after the ignition is turned off. This may be caused by one of the cooling fan relay contacts welding together. To correct this condition install cooling fan relays, P/N 25553347, which uses silver-tin oxide contacts to reduce contact welding. A new fan relay bracket, P/N 25558149, must also be installed to accommodate the new style relay due to the different size retaining slot on the relay case.

Parts are currently available from GMSPO.
