Solved!
Hey guys, sorry to take so long to get back. Busy summer! Two cans of R134a and... problem solved! I agree, who would have linked low refrigerant to cooling fan malfunction. All in the programming, I guess. Low pressure, condition diagnosed as high temp or overheating, and away goes the fan. Oh yah, A/C works great now, too! Wife is happy, she may even think I am smart... just a little bit.
