Hello Chris,
New column switch?
Does not operate properly?
No, I have never heard of before.
The function(s) you describe are correct, that's what the column switch is supposed to do.
Now, I haven't understood your question,
please, what is wrong with your new one?
Q 2: Is your new switch a genuine MB part or a (the Chinese) reproduction?
Q 3: Does your old switch operate proply in your car?
Best,
Achim
