my guess is the dome light is just a bulb problem, i pulled mine out the other day and when i put it back in the end of the bulb broke off... so theyre not the best bulbs in the world..

tips for changing your dome light.. when you open the door the dome light comes on automatically, by pushing up on the lens (where it says 'push') you can turn it off.. so make sure to do that so you dont short anything out.. other than that the dome light is pretty straight forward, to pull the cover off i just put my key in the small slot on the back of it (towards the rear seats) and twist and that pops the cover right off...

speaking of dome lights.. not that its a huge deal but i figured id share this little tid bit for when you're all workin on your VXs, to keep my dome light from staying on the whole time im working with a door open, a penny is the perfect size to hold the slider in the door jamb in the closed position to make the vx think the door is closed
