Just purchased a 2017 ES350 and none of the dome/vanity/map lights work front or back. The lights on the bottom of the doors work. The lights on the panels next to these lights work (the ones with the name or diagrams). Are all the dome lights through the same fuse? I looked at the fuse and it looked new. I have tried cycling the DOOR switch thinking that may have been the issue. I have pulled down the front panel and disconnected the connectors and reconnected them just seeing if there may have been an issue there. Nothing. If anyone has an idea please let me know. Thank you.

 

If you have a volt meter with continuity setting, put one lead on one side and the other on the opposite side of the fuse. You should have continuity across the fuse. If no meter just replace the fuse and check. It's easy to miss a blown fuse. Also, make sure you have the correct number fuse. GOOD LUCK!
