Battery was changed & need to remove fuse so code can be set.

My radio doesn’t work Navi screen is blank. My trunk dvd player is not working. Just wanted to know if the rear player not working , would the radio not work also?

I do not have the FOB for my car and when I went to unlock it after being somewhere for a while for the first time ever after a few months of owning it the car alarm went off and won't shut off no matter what I do I need help figuring out how to shut it off. ASAP!!!!!!! PLEASE...

So I believe I’ve mistakenly plugged the wrong green wire into my climate control and now i dont have any power to cluster my climate controlled dosent work anymore after plugging back up in comes on for a second and goes dim no power to windows or anything checked fuses, fuses are good and one that did blow was replaced but still nothing i than hooked my OBDII scanner to it and have a code now of u0155 that wont go away what next?
