1g AC help!

With the car on and ac on full blast it was cold when I bought it, ice cold. But after 2 days of driving it slowly went away. I checked the sight glass again with the car and ac on, and I saw white foam in the sight glass, according to the manual if I see white in the sight glass I'm low. Well I used a gauge, thanks to the retro valve, and gauge says I'm just right.

But sight glass says otherwise... what's the deal? I put a little free-on in there, just a tad, but white is still in the sight glass.

With the car off and ac on the air blows and at a normal temperature, but with the car on and ac full blast the ac does get a little colder, but not cold as it should be. Like a 74 instead of a 69. I'm thinking a clog so I assume the dryer????

If you were low in the first place then you probably have a leak. I'm no tree hugger, but I'd prefer if you didn't release those gases into the atmosphere because you're nickle and diming everything. Have the thing properly evacuated, vacuum leak tested, then refilled along with some dye and have them check for leaks.

Called autozone and they said just put the gauge to it, so I did. Good to go, compressor clicks.
