Climate Control Problem 97 C230

[HenriFrBenz]

Hello,

My wife has a tendency of clicking on the air duct switch repeatedly and quickly until she gets the maximum air flow from the center duct (dont ask, think wet hair...). I kept telling her this will break the
switch and she finally did this two days ago when she drove the car. Now, at the head and foot postion, air only blows from the side ducts and not the center ducts. Can you please help? I have a 97 C230...it's not worth much but it has low mileage and still runs like a dream.

Thanks

Henri
