Horn blows fuse 47 every time

Post by M7R »

Got an odd one but hopefully easy, every time the horn is pressed fuse 47 blows and the horns dont work, change the fuse and it blows again as soon as the horn is pressed.

I have even removed the relay and it still does the same.

Any ideas?

It doesn't make sense that the fuse is blowing when the relay is removed. look at the wiring diagram below and confirm the car is wired as original.

I will disconnect the horns this lunch, and see what VCDS says.

I even got a another standard horn relay (Couldn't find the one I took out annoyingly) and put that back in.

I will double check what happens with the relays removed as I may have been wrong on that one, I tried it again and I seemed to remember that if either the horn relay or the headlight washer relay are removed then the fuse doesn't blow.

Annoying me now, will be very annoyed if it is the horn has just packed up at the same time as changing the wiper relay, but again at least it would be an easy fix.

so far:

1 horn dead, 1 works fine.

With both horns removed it still blows fuse 47 which from the diagram above is the horn.

Relay 95 removed, and relay 100 in place, fuse does not blow.

one thing I have noticed is that where relay 95 goes there doesnt appear to be any connector to the middle pin on the relay, but from looking at the relay it looks like there should be??? any one able to confirm that the middle pin of 95 should be making contact with something?? maybe I have pushed that pin out by mistake when I put the relay back in?

Right I have had a quick.look at wiring diagram. Remove the horn relay then check that you have the lives to the relay. If lives are present then would suggest remove air bag and check wiring in steering wheel. The horn plate is part of the slip ring and you should have a contact from rear of steering wheel to slip ring. You will also need to remove steering wheel to check condition. If all looks ok then try bridging horn plate and see if horn sounds/fuse blows..if it blows fuse then you have a wiring issue from slip ring to relay

fixed it....

turns out that the photo I found online of the relay locations when some one else fitted a 99 relay did not match mine!! on mine the 95 and 53 relays go the other way round :oops:

horn working now (bar the 1 dead one)

Glad you got it sorted..... based on your earlier post I was going to suggest that perhaps you had the relays inserted wrongly, no way fuse 47 could blow with the horn relay removed :wink:
