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.

Hi Sayid, If you are not using it the container must be leaking. The most common causes are a broken pipe, a defective seal on the washer motor mount or the container is damaged and leaking. Regards John

The first step is to get codes from the computer. When the computer locates a problem it will store a code or codes , letting you know where the problem is and with some testing the problem can be found.
Depending on what the problem is the computer will select limp mode so you are able to get home or to a shop with out causing more damage to other parts of the system.
You will need to go to a shop or a parts store. most auto part stores will scan the computer and give you a print out of the codes.If you get me the codes i will help you in finding the problem.
Good day.

Mass airflow sensor, bad vacuum lines, if you are running a fuel additive it may have fried the oxygen sensor. Keep in mind sensors wear out
