02 Yukon dome light fuse keeps blowing

Every time I replace the fuse(under the hood) it blows almost immediately and no interior light work. When on all doors and overhead lights do work so I don't believe it's one of them shorting. Even tried bigger fuse. Don't know where to look now? Please.

Did anyone recently install any type of electronics (GPS, XM, Stereo, etc.)?

Did have remote start professionally installed two years ago. It still works fine and I attempted to check all connections grounds etc. I kno still could be it somehow but just not sure what to check. Power moon roof doesn't work either. Looked for everything connected under that circuit.

Noticed last night above drivers seat where the little mic for the hands free phone is there is something buzzing. I can barely see it thinkin mabe it's a motor or relay for power moon roof. When I push on it sound changes. Was wondering what it is an if possibly surging an blowing fuse. Roof doesn't work when fuse blows either so it's same circuit??

Did you check inside your cig. lighter sockets/ power outlets for any coins other metal stuff?

Yes I have. I've tried it all. Other night I put fuse in an they worked a few days. Then lastnight the second I stuck fuse in it popd. This is under the hood fuses.
