Multipla no horn help

Hi ive just bought a multipla diesel and the horn doesnt work, tested it at the horn( no power)tested the fuse thats ok, took the airbag off and tested the horn connections( 12v present ) shorted the connections out and it still wont work, im thinking its the horn relay, does anybody know which is the horn relay thanks Peter

I've also just got a Diesel Multipla and the horn doesn't work on that either.
Other fault which may or may not be connected is the red airbag light is on.
I'm wondering if somebody has been having a fiddle with is somewhere as the horn push doesn't sit properly on the steering wheel and is 'pushed in' at the right hand spoke and wont move.

Have you checked to see if it's connected at the horn end?

Yes its connested at the horn end, im just not getting 12v there, i seem to have it everywhere apart from the horn so i think its the horn relay, i just dont know which one it is. The manual shows all the fuses but not the relays thanks peter

Mine stopped working a while back, and I found that the wire had broken just where it goes into the push-on connector on the horn itself. I fitted a new crimp-on spade connector and all was well. (The wire to the horn was pulled very tight from the loom, and the bit of cotton tape around the end of the outer plastic sleeve had come off, putting extra strain on the wire. I teased a bit of slack out from the loom and its been fine ever since)

To find the horn relay...
Open the driver's side glovebox and remove the tray inside.
If you look in the far left corner behind the fuse 'rack', you'll see a largish brown coloured relay. Don't touch this one - it's not the horn relay.
The horn relay itself is on the underside of the circuit board in the area where the brown relay is located - look underneath the dash near the clutch pedal and you'll see it. It should be a black one.

I found another one in the top right of the fuse/relay box.
Personally, changing mine made no difference at all.
After running a lead direct from the battery terminal to the mauve coloured contacts on the horns themselves, one had no response at all, and the other gave a short 'dutt'. Both horns are bu**ered. This is quite common when horns are located at the front of the vehicle.Confrimed this with horns from another Multipla which is being broken relatively locally. Replacement horns work.

One note though. The horn contacts run through the clock spring behind the steering wheel. The clock spring incorporates the wiring for the airbag.

HI
Check the last post of brigbeale find the relay of the horn underside of the board on the left side. This is the horn relay.

The one on the top right side black relay is for the front fog light.

I just found out as my horn was not working until I change the relay.

Both relay is the same 20v small black one. You can exchange both to see its brown or not. My one was damage, I thinks related to the condensation from the air con.

good luck.
