Replace A/C Components - Still Problems
I have an 04 Excursion which I just replaced everything with the exception of the two evaporator cores (front and rear) which were flushed along with all the a/c lines. The sticker under the hood said the system takes 4lbs 4oz of refrigerant. I vacuumed the system for 2 hours and no leaks afterwards. I charged the system with 5.3 12 oz cans of refrigerant and the service manual specs say 14oz of pag 46 oil. When I first started it up after the repairs everything seemed to work fine. I drove the truck a few hours I saw really high pressures 100+/410+ at about 95 degrees.
Today I wanted to get new readings. With the engine cold, the pressures were 85/100 a little low and I probably have a leak somewhere. I drove it for 10 miles and the pressures were 52/340 at 70 degrees. So it seems like I have high/high situation. The Ford service manual diagnostic charts says it is the condenser (inadequate air flow). Could I have gotten a bad condenser from the parts store? Any other thoughts?
