reciever dryer sight glass
My truck has a mixture of mostly R-12 and a little
R-12A in the AC system.
I see a steady flow of refrigerant in the sight glass, and getting 32 PSI on the low side.
Is this about right?
I'm thinking it could blow colder, (HVAC box is clean)

Being that it is still an R12 system, the sight glass should be clear. Try feeding more in, slowly and try to clear up the sight glass. With R134A, you can just forget the sight glass, it will just get you in trouble...Mark
