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?

The front end of my 2004 Yukon Denali was makeing noise. Took the Denali to a GMC dealer and they said it was the front differential. It has been replaced once before when it was under warranty. Now its no longer under warranty and needs to be replaced again.
