I dont know what year model you have but my 2004 Yukon Denali with dual climate control has 2 actuators on the passenger side. The lower one controls the driver side air and the upper one that is a pain to replace controls the passenger side air.

What side is hot air coming from? Give a complete description of your problem with year model, motor size, trim level, etc and maybe someone on this site can advise you. Probably not me since I am a noob in regards to repairing these vehicles but there is a wealth of knowledge on this site.
