The car has been at a shop for another matter. I do not have the tools to fix this problem, but I do like to research the problems as I grew up working on old cars.
This particular problem has turned out to be a combination of problems. The fluid clutch on the main fan was failing. Also one of the two aux fans (passenger side) was completely dead, the other ran OK when connected to 12 V.

The mechanic told me he was probably going to remove the radiatior to fix the fan clutch so it might be a good time to replace the dead aux fan. I have not evaluated the relay or the sensor 1) since it was already at the shop and 2) because me and my $2 volt ohm meter do not get along.

Thank you for the advise.

One more thing. Any of you know how to solve when my wife tells me the car is a money pit......again? Come on sages.

I do not agree, it provide good service. I bought it cheap and have had to repair/replace several maintenence-level issues.
