I have a question about my 2010 Nissan Altima and my air conditioner blows but it blows hot so I thought maybe it was the I need a charger so I got some Freon and it was putting it in it well when the can got almost all the way finished all of a sudden all the freon come rushing back out I don't know where exactly from because it just I could see it I'm at the bottom of the car but somebody had told me it might be my condenser was cracked somebody told me it may just need my vents need to be flushed and I was trying to see if anybody had any advice on what it possibly could you know be wrong and like I said it when the cans almost empty it comes rushing back out all at once and it's kind of like it's over full like it's full and I'm overfilling it. Thanks

Wow, this thread seems like it will get messy; I hesitate to involved!

Are you using any gauges at all? If so, what pressures were you getting (and at what operating conditions)? Were you trying to fill through the low side? Have you checked for where the leak is with a black-light (UV light)?

Assuming the refrigerant did "rush out", then you will be needing gauges and a good vacuum pump to get it recharged again; after the leak is found and repaired. The UV dye/light is often the easiest way to find the leak. If the system did not have UV dye installed at the factory, then I would probably put some in and start doing a charge. As the new refrigerant "rushed out" again, some dye should come with it and quickly show where the leak is.

Do not use any refrigerant or dye with a "sealant" in it!

Flush your vents? Whole can dumps in an instant? Under car is very vauge. Take it to an AC shop. People using cans ruin good systems. Over charging is bad. Oil? You didn't know for sure that it was low on gas.
