I just purchased a 2008 SUT and it too does not have dome, or map lights as this thread entails. I have played with the over-ride switch, checked the fuses CTSY (Courtesy) and IS LPS (Interior Lamps) which all appear to be good. As mentioned above, the 2008, (and I'm assuming the 2009) do not have the TBC 1,2,3 Fuses (Body Control), but they do have CB 1,2,3,4 which are Circut Breakers. However, I am not having any other issues with Doors, Seats, or Power Windows which these circuit breakers control. Having said that, does anyone else have an idea, or a wiring diagram for the interior lights for a 2008/9?

 

Here ya go!

 

Thank you!! I went to troubleshoot it starting with the overhead console lights; bulbs were missing. Checked all four doors, and rear passenger overhead. Every bulb had been pulled by the previous owner. I've never seen anything like it my life, and why when there is a dome light override switch. Crazy, but mystery solved. Thanks!

 

they probably had converted them to LED and decided to keep them

 

Just wanted to say thanks for this posting... helped me a LOT. TCB 2B fuse had me in a panic! Map lights ceiling on open doors and rear door lights were out.
Driver and front passenger worked..
