Your compressor is not working at all. Those are static pressures of R134a at about 88-90 degrees ambient temperature. You have no cooling because the refrigerant is not circulating and the refrigeration process simply isn't happening.john keefe wrote: ↑Wed Aug 03, 2022 9:44 pm Anyway, I've got a fully charged A/C system, but almost no cooling. 105psi on the high side, 100 on the low pressure side. Compressor sounds like its knocking, and never made that noise before. Manuals says it could be the 3-way expansion valve, but I have no way to testing w/o evacuating the whole system. It has a Rapido expansion tank sitting in front of the evaporator & fan.
Are you sure the clutch is engaging and the compressor is spinning?
The Scorpio uses the Nippondenso 10P15E compressor. "E" means "ear mount." The innards are exactly the same as the more common 10P15C ("C" for "case mount"). You should be able to get this sorted but you will need an evac and recharge.
