Fuse box. Take it apart and look for burnt connections, melted solder etc.

I had same last week, took relay board apart and then ordered a used one from ebay as the old one was obviously cooked. It came with a complete set of relays and fuses, all is good again with the blowers.

That looks a bit poorly, just make sure you get one with same part number , could wrong but think they vary a bit.

Yes you do have to make sure it is the right part number as there are quite a few different boxes for diff years manual- auto and so on, new ones are available should you wish to go that route .

Looking at the heat damage to the circuit board, it will need sealing with a Conformal Coating after repair to stop it absorbing moisture.
