AC heating cooling

[Big English]

I have a 2011 PPV and the main issue i have right now is that the drivers side only blows hot air. When i put the temp up she all blows hot, when i switch to cold air the passenger side and rear blows coldish but the drivers side stays hot. AC isnt coming on and flashes 3 times then stays off when pressed. Checked the fuse hoping it would reset a issue but to no avail......

Any ideas before it goes into the shop ??

Yea not enough charge in the system. Likely got a leak. When mine did that, rear ac line above RR wheel was leaking at the bracket that held the line in place.
