Battery issue? Or fuse(s)? Or harness?

Wasn't sure where to post this, nor did a search find anything relavant. Please move if it's not in the right spot.

Anyway, my sister's car (2006) is having some weird issues...

- the key fob does not work
- turn signals do not work
- door lock switch does not work
- brake light is on
- hazards do not work
- wipers work on and off
- mist wipe does not work
- sometimes the wipers do not do a full wipe

Battery? Fuse(s)? Harness?
