The Number 1 cause of Car AC not working is such a easy fix.
Some mistakes are so simple example performing the Recharge in the shade.
Arctic freeze auto AC Recharge Synthetic refrigerant with stop leak, A/C pro refrigerant are just some good brand Refrigerant that can be used.

Is it necessary to purge the air from the blue line first? And how? Seems like you're putting a "blue connector lines" worth of air in the system if the blue line isn't charged with freon first. Moisture in air ruins a/c systems
As a trained mechanic I would never bother with one of those cheap cans for recharging. I’m hooking up gauges and doing proper diagnosis before I worry about charging. This is only for backyard fixes trying to save a buck, and may or may not help.
I found out that when the a/c compressor cycles between engaged and when it disengages the needle has to be in the green either way. While the engine is running and the ac on max cool, between cycles of the compressor for the a/c to blow cold air on max with the engine.
With the engine running and the ac in max cool and fan, the needle has to be in the green even when the compressor is on the cycle with out the clutch being engaged for the ac to blow cold air! 🟩 Remember needle in the green only during compressor cycles!
You didn't have it on the 12 o clock!
This was a great video, and I followed your advice to charge my wife's VW air conditioning. Now if you could only make a video about how to get the bearing assembly out of the steering knuckle on a Dakota, my life would be complete. So would my truck.
I used the A/C Pro can for the first time the other day and it worked great. Easy and cheap.
Don’t use the leak sealer gimmick. Fix the leaks with new seals or components
There's one thing that bugs me about all these charging videos. Nobody purges the can's filler hose. There is air in that hose. Air contains moisture. If you don't use the refrigerant to blow the air out of that hose before charging, you're adding air & moisture to the system. This will make the ac less efficient, and could cause damage to the compressor valves.
Top of the Can suppose to be 12 o'clock ,look like 3 o'clock in the video
