The horn is mounted on the right side ( if standing in front of the bonnet looking into it) on the chassis subframe, quite low down.
Usually easiest to remove the front panel, which sits just below the bonnet when bonnet is shut, to get at it.
BUT, often the problem isn't the horn itelf, rather it's the contacts under the steering wheel. Which you can fix yourslef in 5 minutes, for free.
If so, here's what to do: -
Get a flat chisel or screwdriver and gently pop up the plastic centre section of the steering wheel.
Detach the wire that's underneath it (it's a push fit).*
Mark where the steering wheel sits relative to the centre boss...so you can refit it in exactly the same place.
Unscrew the centre steering wheel nut a couple of turns and pull the wheel up (bang it a little from underneath to ease it up off its splines. Once it's free, remove nut fully and lift steering wheel off.*
Carefully clean the two copper contacts that you can now see and gently bend them up slightly till they come level with plastic outer ring.*
Test it by placing a piece of wire between both contacts; if horn beeps you have done it.*
Replace the wheel, retaining nut and horn push components.*
