I cannot turn on the map lights in the rearview mirror, the lights under the dash do not turn on, the door lights do not turn on, nothing.

Yes, I checked the fuses for the courtesy lights in the floor plan fuse box and they are good.

Yes, I pushed the button on the left side by your knee and nothing.

Have no idea. It's been a while that I noticed they haven't worked, but i just checked the fuses last night and they are fine.

Please help if anyone knows of any issues or how to troubleshoot.

well, we were getting real good at explaining to folks how to get them to turn off when they would stay ON. guess we now have the very opposite!
i suspect you did everything i just did, searched topics (none found). checked fuse position (tried that huh).

all i can do is show you where i think the fuse is on a 2006, which i bet you know, but adding here in case..

Yes, all of the above.

Have you checked to see that there is no issue with the fuse slot itself? That is, check continuity between both sides of the fuse slot. Other than that I'd probably try a battery pull for a few minutes.

Check the bulbs themselves as well. Or even better, for 12V power between the leads. Also check the mirror connector is pushed all the way in. It has to be something stupid... unless your car has been flooded, or on an accident. You can also check all possible grounds, for loose bolts, but you'll need a service manual. Good luck.
