So why not use a temperature switch on the output of the AC itself. It the AC is running and the output is above, say 55 degrees, then turn the fan on?

I thought about that. It is a good suggestion. But what about the times in spring and fall when the AC is mostly de-humidifying the air and not working very hard. The temp will get that high and the fan comes on. That will not hurt anything but it is not needed then for sure.
I am one of the folks that only rolls down my window to talk to someone like a toll booth attendant or something like that. I don't ever ride around with the window open even on a perfect day. I have too many allergies. I drove an un air conditioned 914 for over 20 years. I have had a lifetime of open air driving. BTDT. I an't gong back. Either my heater is on or the AC is on.
A pressure switch might work if I could calibrate it to the high pressures, but that is going to be a challenge to graft into the system. The brake pedal seems to be the best suggestion so far.
