Ac has started blowing hot air

The center part of my car that controls the AC/heat and music display is not visible or lit up ,also the charging port isn’t working

Replaced old wire harness from the front fuse box to the instrumental panel fuse box and then all the way to the rear compartment fuse block. And know the car won’t start and the electrical power steering wheel doesn’t work radio AC heater steering wheel controls and it will come out a park. Can anybody help me with this one please and thank you

Bottom half of screen not working. The screen says AC On; there is no way to switch back to Heat mode. I can adjust the temperature on the dash, but it’s stuck in ac mode!

My car radiator fan stays on to long after the engine is stopped and the coolant gauge shows cool, no A/C.
