Muggle Posted August 10, 2015 Posted August 10, 2015 Knowing how great the french electrics are, I'd be looking for an intermittent short somewhere - have you done any work on or near the steering column? I'm always loathe to start dismantling steering wheels, but that's where the switch is, after all. Be very careful and find the correct procedure before you even think about undoing a single screw, though - you don't want to set off the air bag!Failing that, find the horn itself and the relay system that feeds it and make sure there is no moisture or contaminants anywhere. I'm sure the site experts will know where the cabling goes and where the horn controller is to be found. Good luck KC Quote
coastline taxis Posted August 10, 2015 Posted August 10, 2015 Id go for the comm unit behind the steering wheel. take not of muggie,s advice before you go poking around Quote
