Air conditioning
I have a 1992 F-150 XLT lariat 4x4 with a 5.0 and automatic. I converted the a/c to 134a years ago. Last summer the compressor went out and i replaced it with a new compressor, accumultor, orifice tube filter and evaporator, (orafice tube filter was cause of evaporator replacement). It call for 44oz of R-12 so that should be 33 oz of r134a. I put 34oz in it and the low side is running 55lbs and the high side is running 350lbs and it does not cool. I added the r134a slowly and it never started getting very cold. I vacuumed it down to 30 inches for 30 min before charging it. Any ideas what is wrong
Thanks Stan
