Thumbs down Renault Laguna II - Phase 1 - Electronics - Permanent horn !

Hello again,

OK I drove through a very deep puddle ( near side ) today..

Car was fine until about 5 mins after returning home ( car was deadlocked and switched off ) the twin horns blasted out the estate I live on..

I tried reseting the locks with the card key assuming it was an alarm fault but still the horns continued to blow..At approx 98Db !!

I got in the car and inserted the card key and the horns momentarily stopped as the starter motor kicked in ( presumably the car diverts main electrical power to get the engine turning over )

Anyhow I drove the car to the nearest industrial park ( to avoid ****ing off anyone ) to see if I could suss out this bizarre fault.

I removed the interior fuse 15amp for the horn but still it kept on...

Removing one of the 30amp fuses under the bonnet did sucesfully prevent further damage to my ear drums..

Me finks this is another water ingress problem but questions are..

Horn is located behind nearside headlamp ( anyone got to it or worked on it ? looking for advice here chaps )..

Would there be any other reason why the horns did this !!

Yours disgruntled
