Hey all! Long time reader/first time poster, thanks for all the gems of knowledge posted on here! Been super helpful in my adventures fixing my XJ.
Recently got tired of my 2001 XJ blowing hot air all the time, and wanted to do an AC overhaul! The A/C clutch plate was super rusted out (discovered as I was going for the shim removal "mod") but would engage at times, and system would hold refrigerant, HOWEVER, the HI side was always much too low (less than 100PSI with the clutch engaged). I swapped out the compressor, dryer, and hi-pressure line with a set from UAC. I opted to not swap out the condenser, as the compressor didn't die so it shouldn't be tainted with metal bits, the system appeared to have no leaks, and I have a modded front bumper that's a pain to take off.
Fast forward to a successful install+vacuum+recharge, plus replacing the low+high side sensors/switches, my high pressure side is still too low @100PSI, and I need to overcharge the low side to 50PSI to get the clutch to engage at all (with A/C at max).
Since the low side the system is holding refrigerant and the compressor+dryer+sensors are brand new, is it possible I have a leak in the condenser causing this imbalance? Something I'm missing? I'm stumped!
