The weather was very nice in Central PA today - it nearly got up to 80F - so when my wife and I went out for our 6th wedding anniversary dinner I turned on the AC (didn't think the sunroof was appropriate for such a "formal" occassion). The AC worked fine and cooled us down, except that it would make a hissing/wheezing sound lasting 10 seconds every minute or so. It wasn't a hissing sound like hot radiator fluid blowing out of a leak (don't ask how I know what that sounds like), it was more like the sound you hear on a bad sci-fi movie just before a creepy swamp or bog monster attacks - Very weird. Didn't seem to be driving speed, RPM, or fan speed sensitive, nor did the flow temp or volume seem to change - it just cycled on and off every minute. Anyone have a clue what this might be before I take it in??

Sounds as though your refrigerant gas is low, especially with the quick cycle time.
