I have changed both hooter for 2004 Mercedes-Benz C200 but still not working
By hooter I assume you mean the horn? On Mercedes these are controlled by the AAM or all activity module. That's just a computer module that controls the human interactions amongst other things with the car. Airbags, horns, wipers and all sorts of weird stuff is not directly connected to the switches you press. So in your case the problem may be in the wiring or connector but can also be the aam.UnfoUnfortunately you will need to go get it connected to some version of the Mercedes diagnostic software (star system). This will read a code and tell whatever the issue is. It is not the same diagnostic that the normal mechanic can read and usually only found at Mercedes or shops that deal with euro vehicles. This is a pain and will cost but it might be as simple as the code nearing to be cleared. Then the aam will recognise it is connected to two working horns again and allow them to be activated. Before you do that check your wiring and connectors, look for corrosion and or bent broken pins or wires. I would have to look up the fuse or relay for the horn to tell you but those need to be looked at as well. This is the same stuff a mechanics will do but you are cheaper so it's worth doing.
