A/c wont work

Ford Mustang 2016 ecoboost 70000 miles
Hi, the hot air won't work on the passenger side (driver side works correctly). A few Mechanics worked on the issue, but after a few days it starts blowing cold air again. What it could be?

Heater/AC temperature control does not work

Ford Mustang 2012 3.7L Base Model, Auto Trans 141000 miles
The temperature control does not work, currently stuck on cold. I confirmed it's NOT the blend door actuator (it's not making any noise) it tested good on ForScan and on the bench. I removed fuse #15 for reset procedure according to several YouTube videos, still no luck.

Ac not blowing.

Ford Mustang 2006 GT 200000 miles
I filled freon and it lasted several days. But during that time it shut off on its own then turned right back on. This occurred twice. I turned it on and it sounded as if it was came on but no air blowing out at all now. I figure it must have a leak. Just curious if it is possibly something else as well I should be checking. I recently bought the car so I'm not aware of anything that's been replaced or if they even attempted to fix the issue. Any advice is appreciated.

Sounds like it's needs recharged if it drops below certain level the compromise kick on as to not damage the unit when running it out. I would start with getting recharge kit and properly draining the system of all it's air then recharge it as can tells you to do so. Once system is clear of air you can then replace it with your A/C freon until your level is back up in the safe green area. Once it does you see your compressor starting to kick back on and off make sure vehicle is running and A/C is on max when adding the freon
