I bought a crashed car and repaired it. Since then it starts but suddenly stalls. With the crash, the intake manifold was broken and I have changed it but the one I got was a standard one. Does that have anything to do with my problem?

It is the A/C buttons on my ford fusion 2016 1.5 turbo-boost. The AC buttons not working, the passenger window is not opening, radio tuning/Volume up and down all these buttons not working... some times they work and suddenly stop working all at once.
The radio screen still working fine and i can navigate through it but can’t turn the AC on. They work sometimes all fine and the AC is cold but suddenly they all stop at once!!. I checked the fuses all working fine. I don’t know what is the problem. Can somebody help me please?
