I have had my AC recharged and dye put in there was a leaking Schraders valve and it was replaced. Then the system was recharged but now it is blowing warm air again.

Hello, further testing will be needed to find out if there's another leak in the air conditioning system. There can be many possible sources of leakage. A little bit of extra effort and time will be required to see where another possible leak is coming from. Additionally there are other possible causes of air conditioning systems not working properly. Too many causes that are potentially there to list, so you'll just need to spend some time having testing performed.
