The TOTAL charge for the system is just under 1 can from all accounts. If you need to recharged then you must have a leak. I had to replace the Service Port (High & Low) seals some years ago. The OEM seals were revised and a kit issued for older models so that standard "O -rings" can be fitted from then on. Cost was $11 per port or so then.
I took it to an AC repair shop. They found the leak and installed the new seals that I supplied, vacuumed out the system and recharged everything with the proper amount of "freon and oil for $95. Worth it when you consider the price of other parts should the recharge be done wrong!

Well to be honest I don't know if it needs to be recharged, all I know is the aux fan is not coming on, and that I have cold air on the driver side. I may indeed have proper freon pressure. If it is true that low freon levels will cause the aux fan to shut off then it is probably low, but that doesn't mean I have a leak right? Freon was never added to the car since it was bought brand new in 2005.
