Smile Courtesy Light/Sunroof/Mirror Not Working

In my new (to me) 2001 E320 4Matic wagon, nothing in the area of my courtesy light (mirror, sunroof) is working with the exception of the red "SOS" button lighting up. I have checked the bulbs in the courtesy light, as well as all the fuses in the fuse box on the left side of the dash (door open). Also just discovered the auto-windows-down/auto-sunroof-open feature with the key fob and while it does open the windows, the sunroof still doesn't budge.

Is there another fuse or relay or even a known issue with a wiring harness connector that could be causing all these things to not work?? The courtesy lights in the bottom of the front doors and those in the back work fine.

sounds like your having problems with you overhead control pannel.
there a common problem. there just a plug and play item. you can find them on ebay. junk yard. if you know someone with the same car diagnoses is easy
just swap them over at test your functions. they come out by prying between
unit and head linner. right where the sun roof is.
