Good Day All

Truat you are well

I own a 2011 Mercedes C-180 avantgarde, about a month ago i got into my car after work and not one of my steering wheel buttons worked not even the horn.

I got home and checked all th fuses but there was nothing worng with any of them. I went into my home and left it for the night.

When i got into the car the next morning everything was back to normal. . . After a few days i picked up that this happened every time it got hot outside. So it seems when the temp get a bit high the steering wheel functions stop working.

Does anyone have any idea what the problem may be? Or even some advice where i can start my search for the problem.

Thank you
