Hello,

My gf has a 03 c230. Recently the four buttons on the left side of the steering wheel stopped working. The volume controls on the right side work but nothing happening on the left. Anyone have any clue as to what this could be?

 

there has to be someone here who has had this problem.

 

Hi I have the same problem with my steering wheel buttons. Have you been able to find out what the problem is?

 

It's the contact got dusty. My window cannot open and I blew the switch with compressed air and it works fine now.
