GP38-2s with horn and bell reversed... Why?

Yep, something's not quite right.... I presume you're running conventional . To get the "sound car" working ,revering the transformer leads (or track)

 would correct the problem but..... Is this going to put the other  Weaver GPs out of whack?  Do they have sound?

AC Track wires reversed to circuit/sound board.  G

Agreed.

The whistle/horn function is activated by applying a DC offset to the AC running your trains. This DC offset activated a relay to trigger the whistle/horn in older Lionel trains. The horn is activated by applying a DC offset of reversed polarity compared to the whistle/horn. I don't know if the offset is positive or negative for the whistle/horn or bell functions. You can easily figure this out with your digital multimeter.

Weird issue, never had this problem on anything else. When running the "sound car" that goes with my three other powered Weaver GP38-2s, pressing the horn button rings the bell, and pressing the bell button blows the horn. Any idea why?

I have a Lionel locomotive that's the same way.  One of these days, I'll get around to reversing the leads, but in the meantime, it doesn't bother me enough to take any immediate action.

A simple problem. The power wires to the car are reversed. Or reverse the wires to the track  I can't find if you say anything about what the engines do. If they have horn/bell too then it's the car wires.

Try to reverse the wires inside the sound car and not the track power wires. I have one Weaver engine (a C-630)and it is different then my other engines, so I recommend reversing the wires in the sound car and not the track.
