Battery wrong way.

I accidentally put on the terminals the wrong way, and of course huge spark when attaching the negative terminal. When connected the right way, the car does start and run normaly, and the car works fine. The only issue is that the power steering isn't working anymore, and infotainment screen, and steering wheel control lights aren't working anymore. Button lights on the hidden compartment, and capacitive buttons work perfectly, and they control the HVAC system, just can't see what I'm doing. I've gone through and checked ALL fuses, they are all good. The 300A fuse in the little module on the positive terminal on the battery was blown, so I replaced that set of fuses. Has anyone else ran into something like this?

Fortunately a lot of the important stuff is protected against reverse polarity but not everything and you probably have some damaged modules from reversing battery polarity. I don't want to be the bearer of bad news but don't be too surprised if some additional items fail in the coming days.

Check with your insurance carrier to see whether this might be covered under your comprehensive insurance because it has the potential for getting very expensive.
