New sensor.
Pulled sensor out of housing slowly trying to duplicate float ring influence on sensor, but light still on.
Disconnected sensor: Lamp on.
Disconnected Washer sensor: Lamp on.
Disconnect any combination, washer/coolant : Lamp on.
Lamp now covered with small square of electrical tape !
Fixed bad fan by removing and freeing off stuck brush in holder.
Both fans now run when a/c system needs condensor cooling.
LAMP STILL ON.
