So here's the story. Back when I put my GN back together awhile back I blew out all the lines, put on new o rings, installed a new accumulator and orifice tube, and proceeded to charge with freeze 12. Now before anyone flames me for using freeze 12, I have to say I've used it on 2 other r12 systems and they are still working great years later.
So I jumped the low pressure switch and tried to charge, but I only got 10-12psi on the low side and the cold side line going into the evaporator was freezing up and the air coming out of the vents was warm. Unfortunately I don't have the right adapter for the high side, so I don't know what that pressure was.
Anyway, I assumed that maybe the evaporator was gummed up. It didn't matter at the time because I was pulling the car back apart for paint work, so I let it be. I just ordered a new OEM evaporator and orifice tube from nos4gn. Now I'm wondering if there was something else wrong?
Could I have had a faulty orifice tube? Did I possibly have too much oil in the system? Just looking to see if there is something I've missed. Thanks!
