just recently my denali started blowing hot air out of the front vents,while the rear was still blowing cold air. Is there an easy fix for this?

I have a 2004 GMC Yukon XL that the front blows cool air then it gets hot and goes back. The back air is working great, but it is a separate unit. The dealer recharged the system 2 weeks ago for $140 and now it is back today because it just isn't right. It has to have something to to with the compressor kicking in or a relay. I still have an extended warranty on it and they need to figure out why this is happening so it can be covered and repaired or replaced.
I am having same problem. Not the fan motor cause we replaced it, not circuit board cause we replace it. Please let me know what works for you before I get rid of this thing.
