I had the same problem, and what is happening is that your not getting fresh air in the cab. The resert blend door is not opening letting fresh air in to the cab to help get rid of the condensation that is in the cab of the car. My dealership had to repair a part that had broken in the blend door assembly. A way you can tell if it is working is put your fan on the highest setting and operate the resert button and you should hear the difference in the fan as it is changing from inside to out side air flow. Hope this helps.

Mine is also a '04 limited, it may be a problem with this model year.
