when I removed my front bumper gor cleaning heclights I figured out that my low horn was no more functionin, so I took it out and did any kind of shock to it, but noway it was not working. Then I dissasembled the horn by cutting the meatl ring and found out that the problem was a corrosion problem, anyway then I removed the rust and this time assembled it using boltsa and nuts. now it runs but not like a new one, after learning the extreme price at the dealer I started thinling about finding an onlline shop, does anyone know such a place . the horn is made by Mitsuba electronic, I tried their web site but they are not selling them online.
