Hvae my mot due next week and just making sure everything is ok its had its service but my horn doesnt work. it used to work sometimes but now it just doesnt work. Is it just one wire or is it a big job to get it working again?

Thanks

Simon

use a volt meter or a bulb to see if there is power getting to it. There will be one cable to the horn and it will be earthed to the body.

If memory serves there are 2 behind the bumper/wing on the drivers side
