Car back from body shop - horn buttons don't work

[MuRCieLaGo]

Hi guys,

I just had my 1991 back from a respray. They forgot to connect both hood lights - easy fix, I just plugged them. However, both horn buttons don't work. Both horns are connected.

They were both working fine before I sent the car out.

But it does work when anti-theft engages.

I removed the air bag and tried to cheat around to get the horn buttons working, without any luck.

Am I missing something?

EDIT: I removed both horn buttons, played around a little bit... And now everything works fine. I do not understand why.
