Dash Horn Switch

[mitumatu]

Hi guys

Van is still off road, failed 2 MOT's but am at the last hurdle,
2nd MOT picked up snapped f/o/s spring along with Horn not working fixed all faults from 1st MOT and spring on 2nd with my own blood sweat and tears, its just the horn now which I've had someone have a look at who says no power to horn. I have had limited time on this and has dragged on, so am looking to just fit a Dash horn switch temporary till I have more time to chase main fault.

Firstly can someone tell me if this is the correct Horn circuit for my van (19D 2002 MK2)? taken from Haynes but simplified for my own use.

If so can anyone please direct me as to running new wires from where to where?

My first thought was to connect switch from B17 to 250 cancelling out comms but then thought if problem is before B17 that would be waste of time but would, let me know if its the comms unit at fault but as i said just looking to running new wire temporary would be best.

Horn was working before comms change and has been sent off to Bradford guy and returned same issue.

I don't have same issue as others saying horn works when key in but no ignition, I have no horn period and can chase that bugger down at a later date.

I am not savey with multi metres but I do have one, cheap at that and to be honest someone already tested as far as I know.

Also bit confused as I cant find F17 in interior fuse box, which is why I am asking if this circuit is correct for my vehicle or if I have a later model version diagram?

I already have the bumper off so have full access to horn, hopefully can get time in next few days if people can throw some info my way.

thanks in advance :thumbsup:
