Replaced the AC system, all new compressor, expansion valve, and drier/accumulator and refilled the system.. worked for 10ish minutes, and blows warm again. Can't understand how this is possible, expansion valve didn't seem like the pressure was going through it. Gauges were reading High side normal and Low side at zero. Its a brand new part, and it works. Just not for long. Only other thing I can think of is the old bottle of R134A I'm using may be polluted, heck I don't know. Any advice would be greatly appreciated.
