78F outside today
Something is definitely wrong...

A/C clutch engages (sometimes), but its just ambient air coming out of the vents.

6 months ago I replaced Evaporator, Receiver/Drier + expansion valve. All lines were flushed and everything was working amazing until recently.

Static



A/C On -- Clutch Engaged (vent temps are not cold. A/C not functioning



There seems to be no pressure at all on the low side
As soon as I turn the A/C off, high+low return to static pressures.
What do these pressures tell me? Just low refrigerant or something else?
