Air Conditioning randomly does not work. Have to shut off car, take out key and restart and sometimes works. Dealer claims needed software update but still does the samr thing. Going back for third time Friday

AC randomly doesnt work.

A/C often blows decidedly un-refrigerated air. Problem was diagnosed as a bad compressor, which I then had replaced. The issue seemed better for awhile, but now is back to randomly - but fairly frequently - blowing warm air from the vents, even when set on MAX AIR.
