How would i know if my fuses have been switched? A friend of mine’s ex boyfriend

A friend of mine's ex boyfriend messed with her fuse box and we can't figure out what's wrong. She believes he switched some of them and possibly took a few but we can't figure it out the manuals aren't color-coded or say anything specific about the chips and where they should be placed. Please help!
My car has an automatic transmission.
