On a 1990 Pontiac Firebird Formula with a 305 injected engine, the radiator fan switch is typically located on the engine's coolant thermostat housing or near the radiator itself. It may be mounted on the side or bottom of the housing, depending on the specific configuration. To access it, you might need to remove any surrounding components for better visibility. Always consult the service manual for precise locations and instructions.
