beteween 50 to 55 its the worst i just picked it up from the dealer it only has 12000 miles and has been this way allthe time they had it a week this last time still no fix

My 04 denali has been great. I have 180,000 plus miles on it and bought it new. My problem with the air is that if I set it at a temp.( example - 73degrees ) it will blow nice cool air for awhile then all of a suden it will blow hot air. Very frusrtating when your on a trip and it 90degrees outside. If I stop the vehicle and shut it off, let it set for awhile and then restart it, it will blow cold again, then maybe ten minutes later we're getting toasted! Then a little later we're cool again.. Do I need to take it to a garage or is this an easy fix?

Are the parts available from someone other than a dealer?
