The units fail, but often it is just the connections at the sensors and the plugs that get corroded. Trying to follow what you have done, it sounds like you may need a 4th. Try finding a good electrical contact cleaner and soaking the connections and brush them with an old tooth brush. Let them dry out and try again. Same with the plug connectors on the cables.
