Hello folks this is my first time on the forum and I have a 07 clk 350 and as luck would have it my radio audio has stopped but looks like it should be working as all functions seem in order. If that is not enough the automatic up on the windows has stopped working as well. anybody know a fix to this one???

 

commonly the audio amplifier goes bad in those clks. try pulling the fuse on the left side of the dash. there should also be a fuse chart in there on the left side of the dash.

auto up and down usually only quits when the battery has been disconnected or dead.
try to renormalize them. put the windows up by only pulling the switch half way..or to the first detent. go all the way up then hold the switch there for a few seconds. sometimes itll take a time or 2 to get it right.
