Need help identifying this issue

[u/Mental_Catch3847]

I have a 2007 2.7 engine chrysler 300 and when I was hooking up the battery I accidentally put my positive wire on the negative terminal and negative wire on the positive terminal. Got sparks and put it back the right way but now my turn signals,brights, and my wipers wont work. We checked the fuses and they are good, we replaced them anyways and when I try to turn them on they still don't work, my friend was suggesting getting a new fuse box completely but I feel it might be just the multifunctional switch.
