I have an '89 560SEL. The problem thet I have is the horns. You can change
tones on them, but they both sound weak. Is there something I can do? One of
the horn does not make any sound at all. Also, do you really have to press
"hard" on the ceter piece of the wheel to make the horns works? I love the
car, but I need "want " the horns to work correctly. Am I asking too much?
