horn fuse again

Hi all.
Having replaced the horn fuse for the 5'th time in 7 years I have found that if I press the horn button in and hold it in the horn will only sound for 4/5 seconds before the fuse blows. I would have thought that if the wiring was earthing somewhere it would blow the fuse instantly. Also if one of the horns had failed surely less power be going through the fuse and it would not blow ?.

Any help much appreciated
Andi.

Could be a high resistance through one of the horns. Unplug them one at a time and try it Thumbs Up

if it is high resistance on one of the horns presumably that horn is busted and should be replaced.

many thanks andi Bow down

Thanks for the help Bow down
Replaced fuse and checked the horns, the one behind the headlight vibrates and is loud, the one behind the front grill viberates but I feel is relatively quiet. Perhaps it is partially faulty Question Question .
