I have a\n 06 E350 that is gettting no power to the sunroof or dome lights. I was hoping there is a relay that has gone bad, but I cannot locate it. I have checked all the fuses and they aregood. I am hoping someone here can point me in the right direction to correct my no power problem.
06 E350 no power to sunroof

Just making sure you checked F9 in the rear SAM located in the trunk. It supplies power to the overhead control console.
Also did you look at them or use a test light on both sides of the fuses? Sometimes a fuse that looks good can be a dud.
That is why a test light checking both sides of fuses can be more accurate.
The only other thing I can suggest is to have the car scanned using an MB Star system. The downside to that is dealers charge about 1 hour labor.
Some aftermarket shops have MB Star clones and will charge far less than the dealers.

Welll I checked the F9 in the SAM. It is a 25 amp fuse, I used a multimeter to test it and it was good. I cleaned the connections and inserted a NEW fuse. It did not help at all. I am hoping someone chimes in soon with another idea.

Could be the Roof Unit is faulty. Basically it is the circuit board inside the front dome light assembly. I'm working thru an issue with mine that draws down the battery overnight. Lots of them used on eBay.
Since the board is up by the sunroof it's apparently susceptible to water intrusion. You can inspect it for loose or disconnected wires by removing the mirror and some associated plastic covers. Then it just pops down. There are other threads and videos on ow to do this procedure.
