Update:
Fuse at position 11 checked ok. I ran a line direct from the positive side of the battery to the light (at the black/red connection) and confirmed that it worked as intended. So...I wondered if the connections under the passenger seat had something to do with this...this is what I found:
Click to view attachment I connected the black and blk/red wires and now the interior light works as intended. BUT - I also found the clear plastic connector with a connection that appears to be broken off. This connector is to a bundle of black wires that leads into the larger relay.
So I'm wondering....should the blk+blk/red have been connected along with this bunch? Just wondering since my e-brake warning light is still not functional and i know this bundle under the passenger seat all interconnects with that sort of stuff.
Progress....progress....thanks for all the input!
(edit: explanation - I connected the blk and blk/red wires because they "looked like they belonged together" as they were bare ends and just laying there. But now that I think about it, I'm betting they came out of that clear plastic connector and had just pulled out...but didn't want to connect a line with 12v on it to other wires without really knowing what's up...)
