berlingo horn and airbag fault! Com2000
#1
Hi glad to see there a forum for berlingo
Hope it become a good resource

Sometime ago my airbag light came on when all through the contact cleaning
tricks and tips fix it for a while then it can back fixed it again then it came back intermittent then became a permanent fault
Now I have a none working horn arggh!!!
Taken the airbag of taken steering wheel off clean the Com 2000 rotary connector no joy. I know a new Com 2000 is a lot of pennies for a common weakness of the component.So any good suggestion ?
Also I was thinking I might put the horn on a press button switch on the fixed part of the steering wheel cowling. Can anyone give me an idea how and where to pick up a live feed from?
Any ideas will be appreciated
By the way its a 1.9D 2003 berlingo in Spain Smile
spares are very expensive here as are also the breakers
Cheers

I have a 1.9 2003 berlingo too and have had the airbag light come on twice, it went when i hit the horn at someone pulling out infront of me on a roundabout one time.

I've not had a problem with the horn before but have you checked the fuse for the horn? In the Haynes manuel it says it is in the passenger fuse box and is F17 should be a 15A fuse

Hi Lliam
Thanks for the reply
Wish it was that simple the Comm 2000 are a know problem several people have got away with a little of WD40 sprayed into the rotary connector beneath the steering wheel or cleaned up the horn connector beneath the air bag
unfortunately mine is more terminal I'm hoping someone has be able to isolate the fault on the circuit board or connector ribbon or suggest a bypass?
These unit are here it Spain $350 to replace

Hi Jock
Have you taken the the horn spiral cover of and prised out the centre core
This where I have got stopped also there what looks like a push fit clip arrangement that fits on to the circuit board but I am concerned that if by too much pulling and prising it will snap (Result £250 com2000 unit )
Here are some picture of the similar unit taken out of a 406
