You need to get to where the compressor clutch engages magnetically with the compressor pulley. That takes a working fuse/relay and enough pressure in the system to get the ok from the low pressor sensor to engage. The car needs to be on and the AC needs to be on.
You can buy a $10 can of R-134 at Walmart and put that in to get the minimum pressure but you could also have a completely full system with a blown fuse that wont allow the clutch to engage. That's bad to overfill.
Just go slow and ask questions.
When you buy a gauge set get a vacuum pump too. Habor Freight has a $20 vacuum pump that is adequate that works with your garage air compressor. The electric ones are better and frankly buy the $100 one vs the cheaper one.
