Well, per the pic, you certainly don't have enough pressure in there, yet!Started the conversion on my 4/93 80 from R12 to R134. Compressor was weak and I believe there was a combination of R12 and R134 in the system from the PO.
Had the refrigerant pumped out at a local shop. Dismantling and flushing All
Components .Changing out as needed evap, condenser. Have both in hand JIc they don’t clean up and test out. Swapping out New O-rings, compressor, pressure switch, drier, expansion valve, and inline filter.
Compressor runs continuously, makes coldish air, but doesn’t get up to operating pressures. Issue could be the expansion valve sticking, maybe the pressure switch but it’s low on what should be R12 also so I’m biting the bullet and converting it to a post 5/93 ac system.
I’m Planning a trip out west this August including SAS 3, don’t want complete failure on the trip.
