Thanks for the input, Dave. My temp sensor reads fairly close, typically
3-4 degs. high. It was reading 113, not sure what real temp was, but it was
brutal. The air would come cool for a couple seconds then immediately go
warm. Manual cycling did no good. It happens so rarely that it is hard to
check; I should have pulled into a Ron Mac's and checked the clutch,
although I'm not sure what temp would have to do with the clutch. I suspect
it is a heat related electronic failure.

> A few degrees ambient temperature change is not going to have a
significant impact on a/c performance. If the outside temperature goes from
100 to 105 degrees, your vent temperature will change a few degrees... it
will not go from working fine to warm air. Your problem appears to be a
component failure due to heat saturation. I would investigate two things
first: the ambient air temp sensor, and the a/c clutch. The ambient air
sensor will be easy to test because it will send the EATC a false reading
when it goes into failure mode. The next time the heat gets so high that the
a/c stops working, hit the button on the EATC to see what the sensor is
telling the EATC. If it reads a proper temperature, you can try the
"tap-test" on the compressor clutch, or even cool it down with a can of
keyboard dust remover. Might also have a bad electrical connection in the
chain.
