I have seen the front sam control module heat up and go out causing this issue but to be sure let's do a CAN scan which goes through the entire car and shows any faults with the HVAC system. The scan is easy to do check out this guide and video. Also, I have included the A/C wiring diagrams so you can see how the system works.
