freon leak on 99 grand prix se

[chedder]

my ac is leaking on my rand prix and i cant find the leak... ive checked the condensor, and the compressor. the valve stem was leaking so i changed that and it still leaks, but not as fast. im still finding freon on the valve and dont know what to find the leak. also the passenger vents in the car blow super cold even when its low on freon and the drivers side vents dont blow no where near as cold
