Is mine the only one that has a sight glass for checking the freon? That makes it a lot easier to know when you have enough freon in the system. I wish that all AC systems had one.
The sight glass is NON functional on a 134a system. A fully charged 134a system will still have bubbles in the sight glass. Doug
