Hi, I have the car listed above C class not AMG. The sunroof isn't opening and in California there's a big rainstorm right now so that's disastrous plus the warranty for the car just ended, so cha ching cha ching if I go to the dealership, lol. Can you please help? Please list possible suggestions, advice along with steps and pictures, thank you so much. I'm thinking the sunroof motor, but I do much about working on a Mercedes. Thanks again, you guys are very much appreciated.

Hi,

Have you been able to check the fuses in the passenger side fuse box? There are two of interest. If you haven't, start there.

I attached the wiring schematic for the sunroof. I need you to check the two fuses I highlighted. In addition to checking the fuses, confirm there is power to and from them.

Here is a link that explains how that is done:

Let me know what you find.

Take care,

Joe
