I'm baffled that it's so hard to find a diagram of the fuse box. I saw a link in this thread but the server was not found.

I see multiple places in google image search that show the horn relay as fuse 52 under the dash. My car has no fuse in that slot, but I saw a photo of another person's car and they didn't have a fuse there, either.

Can anyone point me to a functional link to a fuse box diagram? 2012 jetta tdi.

There are just too many to list....
Yep, the NCS Jetta has pretty weak horns. Weak wiper motors, too.

Context to your question is always helpful.

I found wires that were cut (presumably either by the wreck or after a fire/short that the wreck created) and respliced in a most half-assed way, so bracing myself to explore this mess. I found one horn wire had not been crimped well at the splice and pulled loose. When I put it back together I lost the click in the dash from pushing horn button. There are two brown wires that come together in a plastic tube (apparently factory) that may be reversed?
