Q: The buttons you press for ac to come on isn't working... on 2005 Hyundai Sonata

I was putting Feron in my ac and the hose popped off while charging it. The ac was on Max while I was doing that. I placed hose back on and continued to put Feron in. I turned my car off when I was finished. When I started my car, the buttons that you push wasn't working or lighting up and the ac wasn't coming on. I change the small red fuses inside the car and under the hood and it still doesn't work. Can you please help me figure this out. Thanks

Do you mean your charging hose popped off? And was the compressor running
when you were trying to charge AC? Did you have a guage hooked up? Did the
button work befor this?
