Both front vents blow ambient air when turned to cool, and both sides blow hot when adjusted to hot.
All rear vents are cooling properly.
If I have a leak would the entire system run dry? Or could the leak be isolated to the front system.

I have seen the ambient light/sun load sensor or one of the vent temperature sensors go bad and cause this problem to find out which one is bad we need to do a CAN scan, this will tell us which sensor has gone out, you can get a CAN scanner (Controller Area Network) which will work on most cars from Amazon.
Here are the A/C wiring diagrams so you can see how the system works and what parts are involved with the system. Check out the images (below). Please let us know what happens.
