'95 Gs300. Odorless, Visible Air Coming Out Of A/c Vents

[Smyurick]

Hey folks, just recently, on my 129000 mile GS300, a odorless, visible air/gas, whatever.... started to come out of my A/C vents when my car was operating normally, as far as I know. I recently replaced the radiator with a OEM style replacement, about 500 or so miles ago. My heat control switch had some residue on it, and after cleaning it off, i found out it has a very tiny leak on it, and for 50 bucks, i would rather not fix it if its not that big of a issue. Anyone know what could be wrong with my A/C? Oh and by the way, I turned off my A/C and it still was coming through the vents, just a little bit.

Thanks

Sam
