Can someone possibly give me some suggestions. I have replaced the A/C Compressor (New) Dryer (New) Pressure Switch Fan Switch (On Dryer, New) Expansion Valve (New) Flushed the system with FJC and plenty of air Vacuumed for at least 2 hrs. Fresh Mineral Oil (approx 6oz. Total Dryer and Compressor). Unfortunately R-134 Site glass does look as if there is some air but flowing nicely, System does not leak has held full pressure for a month now. I just can not get this thing to blow cold Just cool! Is there an internal switch to the climate control I could be missing? PLEASE HELP!
