SOLVED - Trifecta with no Air Conditioning?

[ChevDog1]

I have some really strange stuff going on in my car. It started a few weks ago, with the A/C acting strangely. It wouldn't allow me to direct air from the dash vents, and sometimes I think the compressor was shutting off, as the air would suddenly get warm. Most of the time it would corect itself with a key cycle. A few days ago, when driving past some windows, I noticed that my hazard light were flashing. When I looked at the dash, the indicators were not on, and the hazard button on the console was off. A key cycle corrected this and it hasn't returned.

Yesterday, about 100 miles from home, I noticed it getting hot in the car again, and the engine sounded like it was revving a bit high. When I looked at the dash, I was astounded to find that my speedo and tach read zero, and I had the trifecta of DSC/ABS/Brake lights. I tried to put the trans in Sport mode, and also to manually shift it, with no response. Then the IC beeped and showed "trans failsafe prog". I pulled over and cycled the key - no change. I then disconnected the battery - no change. We got back in the car and it took off in what i think was 4th gear. After some time, the A/C came back on (as did the tach and speedo). This repeated a number of tuimes on the trip home, but the trans would not shift. It only has park, N, R, and 4th gear. The cruise control light will illuminate on the dash, but it does not function.

Knowing that the battery or alternator can cause stuff like this, I had the battery teasted, and it is good, and I checked the voltage at idle - 14.2V ( alternator was new 1 year ago).

Sorry for the long post, but I am at a loss as to what could cause all of these issues at the same time - have any of you experienced this? Any ideas of where to look, or what to test for?
