Air Conditioner Alright my air conditioner has been running poorly lately. Went to autozone picked up the R-134a with stop leak just in case there is a leak. So I got the cord to hook up and transfer the stuff. Get it all ready and start doing it. Turns out it didnt put any in it took it all out. My A/C blows out normal air. Not cold at all.
Am I doing something wrong? Put the end on, the cord put the whole in the can, opened it more then put the quick release end onto the cap.

The compressor needs to be running when charging. You should have pressure on the gauge even with it off, and it'll drop when the compressor comes on. If there's no static pressure at all with the car off, then no refrigerant in the system and probably have a leak, and the pressure switch won't let it operate.

Ok your first post makes no sense at all.
And I have to say that people who 'have no cold air' and run out to put refrigerant in are not doing it right, to put it nice.
You say it took it out? That 12 ounce can would have blown up, theres no room for more, so it didn't take it out.
Are you actually saying you still have a full can of 134a when you were done?
You need to hook it all up, screw the can tap valve all the way down to pierce it, then screw it back up.
The compressor has to be running in order for the refrigerant to go in.
You're better off taking it somewhere. One, because freon doesn't just leak out and then stop leaking out, the leak has to be fixed so even if you did get it to go in it would have just leaked out again.
Or two, a pressure switch is bad keeping the comp off, three comp clutch is bad, 4 relay, fuse, wiring, comp valves broken (not pumping), should I keep going?

Im going to take it somewhere today.
I think you are making a good decision to take it somewhere.
I've done non automotive a/c and refrigeration work for 15 years, and I've made a few custom automotive a/c systems.
What most people don't realize is the mechanical part can be done as easy as any other repair to your car, but the synthetic oil, refrigerant, and outside air can all react to form a barrier that prevents heat transfer. Heat transfer is what makes airconditioning possible to put it short.
