Car horn when pressed doesn't work (but alarm/locking from key - horn sounds); airbag light on; passenger front window regulator off track? Chrysler 2008 Sebring sedan 2.7L

I need help fixing these things on my own. I'm a single mom/nursing
student, very handy, I know I can do this - but I want to ask first before
assuming what's wrong. The car horn doesn't sound when pressed, but
works fine when locking/sounding the alarm from my keys. The passenger
window stopped going up yesterday (motor works fine, but the window
seems to be off track?). Last weird thing is that the driver's side visor light
went out 2 days after the horn issue started. All issues new. I'm hoping
they're fuse related. Any links/advice/etc would be greatly appreciated!!
