In most of the time that I have owned this car, I have not used the A/C that much. It worked last summer the 3 times I can remember using it. It's been fairly cold around here lately. It woudl be getting close to a year ago that I last used it. It could have leaked down, and I just didn't notice.....
Another possible problem or symptom I noticed while my sister was driving the car today was that I didn't seem to be getting any major amounts of heat on the passenger side. The drivers side was set a few degrees cooler, and was much hotter. The passenger side was only blowing moderately warm air.
Duovalve perhaps?? Or the aux pump??
