Hi all go in the car today and my horn isn’t working not sure how long for just wasn’t there when needed this morning!!
Checked the fuse and that’s fine checked if getting power to the squib but I’m not any ideas before I start trying to chase it through the loom

Horn is in passenger side wheel arch if you remove the front liner.

Check the connection and give it a tap.

as above that is usually the issue, clean up the connector etc. If the arch liner is broken they usually get filled with water and shite
