Hello, my name is ***** ***** I am a professional here at Just Answer. I have noticed that your question was not getting a response and thought I would see if you still need help with this.I apologize for the delay and I hope I can still assist you with this here. In order to determine what is causing the AC to not blow cold the first thing you need to do is to connect a set of Ac pressure gauges and read the systems pressure. Normal pressure on a full system with the AC on and the compressor running should be right at 35 to 40 PSI on the low side and right at 200 to 225 on the high side. If you can check the pressure and post back with your reading I will see if I can help you with this problem you are having.
