Hi Guys m a new member here. And m looking for your help, I have got a clk230, avangarde convertible. x reg. and I need your urgent help and advice. The problem i have got is: None of my 4 electric windows or my roof work, they do not open or close. However if I disconnect and reconnect battery everythingwork, but when I leave the car for an hour and more when I return the nothing work again.

I would like any advice I can get so I can able to rectify the problem,thank you all in advance.

Not sure but try disconnecting the battery again and following reset codes for the power windows found in the manual. i thought i broke my sunroof disconnecting it from the headunit of my c230 and then i learned they needed to be reset.

I will try that, however i haven't got an manual for the car. have you got a link or a website where i can get this reset code from?.

Here's the link!

Not sure what year your car is but if this isn't it just google synchronizing power windows + year and model.

Best of luck!

any luck buddy?
