Question about 2005 GMC Yukon
This problem started out being intermittent and now the passenger side blows hot air at all times. I have dual controls but it does not seem like the controls affect the temp at all. I think when the air conditioner is on that the air is cool but dont remember. Is this a temp control door that is staying open and is this a DIY fix?
There is a door called the blend door, it controls air tmerature, it may be defective or the electric motor that moves it..

On some duel systems when the freon gets low one side will work and the other side not. Something toi check if the blend doors are fine.

I have had this problem. I am not a mechanic...so to correct the issue temporarily, I simply turn off the car and restart. This has worked everytime for me. In extreme cases, I think you can also remove the AC fuse and start the car, which will also reset the computer. I also think that by taking the climate control off the "AUTO" setting has worked in the past.

diverter is out of position for that specif duct. It may just be stuck. If vacuum controlled, make sure hose is in place and there is vacuum present Good luck _Ned_
