I have a 16' efan on my 89 FC vert and the Flex-a-lite fan controller 330095 with relay /probe that was installed crapped out last fall . Something wrong in the relay holder wiring for the probe. I got it to just come on with ignition for now but want to put in a new controller . Reading the reviews of the same controller have a lot complaints for failing. Cant seem to find one that people haven't had trouble with Any suggestions for a well made controller ? I don't mind paying a little more for something I can count on not to fail.

 

When I had the stuff apart I welded a bung onto the radiator to use an old VW thermoswitch.
