Several things not working correctly after Battery Replacement

I did the battery replacement and now I have a few issues.

1) the far right of the touch bar does not illuminate, its essentially just the part where the siri button is, if I touch it, siri activates, but there is no illumination. I tried reseating the cables that I thought were related but no dice.

2) the right speaker has no tweeter now. I can still hear low end but there is no high end. This particular step made me super nervous when removing the cable on the right speaker (left side when working upside down) Is it possible to reflow the solder under this connector and see if that improves it?

3) the fan on the left side of the computer is blowing at 100% speed all the time now.

I tried resetting NVRAM and SMC (although I am not confident I actually reset anything). I am currently trying to drain the battery to 0% and let it sit for a few hours dead hopefully that maybe will reset the SMC.

Also with this amount of issues is it possible this is a software issue? Really hoping to be able to solve these issues as I don't really know where to take it in for repair.

Thanks

EDIT:

Took the laptop in for repair to Mac Melrose where I am being told the reason the fan spins up to 100% is because the battery was replaced with a non-apple product, and that by putting in an apple branded battery at $715 it will fix all the problems. Why do I not believe them. Can anybody recommend a shop that can repair the actual problems with the laptop?
