Anyone have knowledge of the AC system in a LR3? The system sometimes works, other times not. No real rhyme or reason on when it works or not. I finally had a chance to throw some gauges on the system and this is what it read. About 20psi low pressure, 175psi high with ambient temps around 78degrees (system was working). While checking pressure it started blowing hot air and the low pressure rose to 80+psi and the high side is 150psi. While it is blowing hot if you turn the ac off, let it sit, and turn it on again the low sides starts to drop (sounds like the compressor is running) then the low pressure rises again (still blowing hot air).
I suspect it has something to do with the compressor either not engaging or not being told to engage. Any tips or suggestions?
