Im tryin to get my AC goin but ran into a problem. Two but one is a easy fix. The Big problem i have is this. The system is fully charged. When i engage the compressor with a pressure gauge attached. I can see the pressure go down slightly then it goes to 0 PSI and then it shows a vac. When i go in the car to check if its blowing cold its blowing hot hummid air, Wich is outside air. When i look at the dryer peep hole i cant see it moving at all. Is there something im missing

 

Sounds like a stuck, or clogged expansion valve. Do you have a high side pressure reading?

 

May have found the problem. I dont have a high pressure side fitting as of this sec. Bout i didnt evac the system. So theres a crap ton of air in there. Ill be getting this all done soon. For free. Gotta love knowing ppl lol. Ill update if its fixed or not
