in last few months my AC has been blowing warm. I refilled it and it lasted a week or so. Then I added stop leak and it lasted a couple day. Then we added stop leak with dye but with the light and glasses we couldn't see anything, there was a little around the port but think that's just from when we added it. I removed the radiator cover and didn't see anything.....none around the compressor .......where else can it be escaping?

only other thing I notice but not sure if its normal. when I turn off the car I get this wheezing sound from dash and more often then not I find my vents closed even though I didn't close them.....is that the o rings failing in controller
