connections under seat will not stop horn working. suspect possible fault with earthing connection on steering wheel

Connections under seat were in ref. to air bag light which are a very common fault in different makes .

assuming horn fuse is ok and you are getting a feed to your horn then check your cim pack as these can play up intermittently,it may need a software update or possibly a new cim pack
