That was a practical solution, but it didn't ultimately get to the source of the problem, which was apparently that of the fan control circuit.
How did you wire them together, and why do you feel the fan control circuit had an issue?

I don't use a/c, but could use the fan on long hills. I'm thinking to take the a/c out and see if the extra space helps the engine keep cool.
