Exact same symptoms here. Wife and I made a 2 hour, each way trip week before last (I also have the evap core and evap valve replaced) and even in manual mode, with the fan at a set speed, the A/C would randomly start blowing about 3x more air volume. Even my wife commented on how strange the A/C was working. Mine also still freezes-up, from time to time. Typically when it is cooler rather than hotter.I had evap core and valve replaced last week. I drove it from Wyoming to Nebraska (900 miles) after the repair. It did not freeze up on me, but it still was not right. It was a relatively cool day (mid/low 70's) the whole trip which is why I suspect it did not freeze up. I still experience random high to low surges in the air output and volume. Very frustrating. I'm driving back to Wyoming in nine days. We'll see what it does then.
Well I drove back from Nebraska on a mid-80's day and did not experience a freeze up. That's the good news. I have not had the opportunity for a long (2+ hours) drive in the 90's to truly confirm a fix. I still feel it is not working properly; specifically I still get the random high and low surges in the air output and volume. I also feel if I have the a/c set to 66 degrees on a temperate day I should be freezing my ass off. That's not the case. I'm cool, but I think I should be cool at a 70 degree setting. I'll continue to follow this thread. I still think there is more to this story.I had evap core and valve replaced last week. I drove it from Wyoming to Nebraska (900 miles) after the repair.

Mine hasn't had any issues, a 22. It's been 110 plus here for over 2 months and it cools fine.I am more and more pleased my 22 took 9.5 months from order to delivery. I have yet to experience any of the problems everyone else speaks of to include AC issues. 7500 miles and counting.
