Evening all ! Can someone help me with the location of the horn on the car please. Just popped out and I’ve lost the low tone aspect of the horn. Can’t seem to find any diagrams or videos on line guiding me to its location. Hoping it’s just a loose wire but if I need to change it I’d like to know where I’m looking and what I need to move to get to it. Thank you in advance guys.

Very often behind the front bumper - perhaps with grilles in front of them - inboard of the corners and low down. 
If they are there, they usually get subjected to the elements and fail. 

Thank you, a miraculous recovery today so I think I’ll take a look and see if there’s anything in the way. My external temp sensor has been out of kilter of late too so there could be something in the same area obstructing them.

The effects of Northern rain Chris? 
Expect horns to be rusty if you find them there.

A common fault on two adjacent electrical devices often indicates a poor earth connection.
