1976 Buick Electra

Post by Mamrak76 »

Working on this Buick Electra. Been converted to r134a from r12. It has a VIR on it. It was working fine then it has an intermittent condition where it goes vacuum on low and stays normal on the high. -20 and 200. I think either the VIR has a problem or the office tube. Where is the orfice located? What’s the problem with these VIR’s. I will add a picture
