We have installed everything new at this point the A/C turns on but all it blows it hot air I assume it's the same air from outside. Does anyone know what electrical issue can cause this?
Does anyone have the A/C wiring diagram?

Hello, sorry to hear you are having problems. I have uploaded the diagrams for the Automatic HVAC system. Is the compressor turning on now? If so, does the large A/C line close to the expansion valve get very cold? If the line is getting cold, then you may have an issue with the blend air door(s) or actuators. Please let me know what you find.
