So on two occasions my AC has just about quit working altogether (warm air blows) and then shortly after I get a hot engine temp warning on my 2008 S80.
The first time, I had it towed to the dealer and they said it was a software issue. They updated the software, and now, two days later....same problem.
I shut the car off for about ten minutes, and then restarted it. I turned the air back on, and it seemed to do fine, and did not give a hot engine temp warning.

Anyone have any ideas? Any thoughts? I'm just about desperate in this extreme Tennessee heat at this point.

Thanks!
