That is exactly the way it is meant to work. If you are like me and want nothing but cold air blowing at all times in warm weather, you set temperature to the lowest setting ("LO") and adjust fan speed as needed.
Any temp setting above "LO" cycles the compressor on and off as needed to keep your set temp. This makes the air feel like a mix of cool and warm air, as you mentioned. Setting temp even one degree above LO will cause this to happen. That may be ok when the outside temp is 58degF, but not when its 88degF. I want icicles! Set it to LO and you will get just that.
Also, once you set it to LO, press the "Sync" button (if you have the 8.4 radio) to ensure both driver's side and passenger side are set to the coldest setting.
