Electrical issues with 2019 International LT Series

I have a 2019 International LT Series, and I've had several electrical issues happen within the past 3 weeks. The first issue I had was all the cigarette lighter sockets that I use to charge things or power with, none of them work in the truck. Then I would push the button to roll down driver side window, passenger side would come down, then the passenger side control to the window wouldn't work, then the window will go down by itself without touching anything. Then the final thing is my premium instrument cluster, it has a joystick looking thing that allows me to go to different menus, and select whatever menu I need ect. Well now that doesn't work and the only thing I can view now is digital numbers for my speed. I've checked all fuses, read the manual ECT...I called an international service tech and of course they would rather I take it to a dealer. I'm really hands on, I like to learn new things, and fix things I'm capable of on my own...so in the long run its its saving me money if I can do it myself....if anyone can help with this issue I'd appreciate it. I just registered onto truckers report and i see a lot of people helping one another, and I like to see that. So thanks again in advance

 

You would think so, but unfortunately my mileage exceeded the warranty.
