Jerry-

That is exactly what I was missing! Now what that mechanic said makes sense -
something about how the fan will just stay on all the time now because of how
he "fixed" the switch. I think what he was talking about was that the
thermostat or whatever it is that controls the cycling on/off of the A/C unit
would always stay on the max setting. He apparently didn't want to get the
right part in there. So when I run my A/C it is always on MAX. What part
would need to be replaced to enable it to be used at a lower setting?

thanks for that revelation!
