I was just wondering if it is normal for A/C cold air coming out the vents to be six or seven degrees colder out of the passenger side vents than the air coming out of the dash center vent and the driver side vent? Also, is there a common place that freon leaks from the A/C system in the C5 model?
Colder passenger compared to driver side is an indication of possible low r134a charge. There are many possible leak locations. One of the more common based on the number of Forum member postings I see seems to be the compressor. It has multiple o-ring joints, a couple of seal washers, and a shaft seal.

More detail needed:
1)How long have you had the car?
2) Is this manual control or auto (blue digital display) ?
3) What is the temperature coming out of the center duct (above radio)?
4) Is this a new concern?
5) Have you checked the high/low side pressures with gauges?
