No heat from vents

[SuperV8]

Does any know to find out which AC gas my car uses 2014 i read it could be either old or new. Any way to find out? Also an still stumped on the cause of my issues

Those blocks are nothing to do with the amount of AC refrigerant gas in your system.
The car can't tell you how much gas you have left.
If you haven't had a re-gas in a few years - then as I mentioned previously, this should be your first 'go-to' for poor/no AC cooling.
Cars AC system's aren't hermetically sealed like your fridge refrigerant so do slowly loose gas over time.

A bit of further investigation I have noticed that the cold air blows much more powerful than the hot, when you turn the dial from 1 through to 6 you notice the difference when on cold. But when hot is selected going through the 1-6 dial you barely feel any air from 1-4, and then at 5-6 it's slightly more powerful but nowhere near how powerful the cold is. So although I believe one of the issues is now AC needing regassed what could be the issue with air power? Jammed flaps? And if so how to fix (they aren't the automatic controls) any advice would be great and much appreciated.
