I found it in the engine compartment fuse box labeled BCM2 (body control module 2)
IT SHOULD BE UNDER THE DASH ON THE DRIVER SIDE. I BELIEVE IT'S LABELED COURTESY.
Dome light removal video: http://www.youtube.com/watch?v=wv2CU9VAHFg
On the centre of the ceiling (light for rear section)
passenger side near the left foot behind a panel there are a set of fuses the dome light is located ther with other lights
You can remove the dome light, in your 2000 Chevy Tahoe, by inserting a small screwdriver into the locking slot. Gently pry downward with the screwdriver.
the dome light bulb can be burnt out or the door pins are sticking. check it out.
Three different fuses control the power windows, dome light, and remote trunk release on a 2000 Taurus. The trunk release is at #26 in the fuse box panel in the dash. The dome light is at #37, and the power windows at #33.
Yes, all electrical parts in the vehicle are fused.
The dome light diagram is quite simple. all 4 of your door switches are grounded to the body where they mount. the wire leads run threw the insterment panel junction block, then out to the dome light. the dome light has a 3 contact switch, one contact being "OFF", second contact being "DOOR" and third contact being "ON".
Passenger side fuse block, 10 amp fuse labeled "Body".
It is in the fuse box located on passenger side kick panel- it is 10amp fuse that says "BODY".
the seat belt sometimes makes the light stay on
