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.

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.
