AMG C36 Loss of Main beam and Rear Electric Windows!!!

[three pointed star]

Heres a funny one. Have just had a friend report that his Main beam and Electric rear windows have stopped working on his C36 (C class 202). Can this be related? It was serviced/MOT'd 2 weeks ago, and both at that time were working. Where should we start looking. Thanks for your help/thoughts.

Check the fuses first on the main beam .Is the child lock switch in the proper position for the rear windows.

Thanks Landover, have already suggested the rear window child lock, and that's correct. Strange how the 2 things should go down together.

Can't see why they are not connected. I would have a go at the lights first. If i can find out any more i will post it on for you.

Thanks again for your thoughts Landover, will get him to try/replace main beam fuse. Would love to chat, but past my bedtime. Thanks for now.
