When the A/C quits, whether it's after just a mile, or after four hours
of ice cold air, what I get is definitely plain ol' outside air. Whatever
the temp is outdoors. Definitely not heated air.
The system has "froze up" once or twice. Even with the blower on high,
there was little air coming out. I turned it off and waited a while (half
hour?) and the blower blew the normal amount of air again. However, it
usually blows up a hurricane whether cold air or street air.
And - on a few occasions, I've had "fog" coming from the air outlets.
Like my own private disco! That has happened only during a fairly lengthy
session of actual air conditioned (cold) air. Unfortunately, I have no
idea of whether it was humid or not. When you're on the road on weekends,
it's hard to get a local weather forecast. All the radio stations do
nowadays is record the "weekend weather" on Friday afternoon and let the
automation drop it in in the middle of "59.775 minutes of non-stop
hits". I have no idea whether the compressor is still running when that
happens (the A/C, not the non-stop hits).
I would doubt that the climate control sensor is defective. In winter, my
little interior/exterior Radio Shack thermometer is always within one
degree of the climate control setting.
although I had it checked last summer. I'm taking the car in Thursday for
some other work, so I'll have that checked again.
Thanks for all the ideas. It's not that I can't handle the windows-open
breeze at 75 mph, it's those hot little trips around town that make A/C a
necessity. And to my brother in Arizona: dry heat, my #$% - heat is heat!
