Man tgs airhorn

hi guys, I’m driving our MAN TGS this week as our driver is on holiday, he has decided to turn the airhorn off for some reason, the switch on the dash doesn’t do anything, I’ve checked all the fuses and had a look round but cant find anything, the horns were fitted from factory, does anyone know what he could of done to disable the horns, the road horn works as normal. thanks.

check behind the o/s seat in the corner thats where the air supply manifold is he may have strangled the air supply kinking the pipe ■■?,just peel back the floor covering should be a plastic 4 way manifold feeds seat, pto etc.

Sounds a bit extreme just to stop him playing with his horn :laughing:
