@strmwzrd Did you get any resolution on your AC issue? You mentioned in a previous post the TXV didn't help, but your technician's writeup seems to suggest that it was needed.
Just had a couple days of 90F+ here in upstate NY and something is just not right with the AC in my lightning. I've also noticed that my AC compressor is much louder than it was last summer. I drove for a couple of hours yesterday with my wife and kids and had the HVAC set to Max AC, and we just had warm air the entire time. It was particularly uncomfortable, and even putting the windows down for the classic 4-60 air was of little relief.
I think my notable compressor noise these days is from it being commanded to run at max speed -any- time the AC is engaged, versus throttling back after the cabin temp setting is satisfied. My guess is the HVAC module ends up calling for wide open compressor speed as a result of a different fault that has reduced the cooling capacity (i.e., short on refrigerant, maybe the TXV, or a restriction).
I'd like to make an appointment at my dealer, but would like to be armed with information on what solved yours. If my appointment day is only 70F outside, they're going to send me home without reproducing the issue.
