i've searched on here about these things not working well, and i've seen the rivets blamed, and the door switches blamed.

when i got my montero, the light didn't work. someone had already squeezed the rivets, and the door switches work. when i multimeter the terminals going to the dome light selector switch, there is power where it should be. the only thing that is left then is the actual ceiling switch. i took apart the switch, you know, it has a detent ball and spring that provides the contact between the different points. well, i cleaned the ball, and cleaned the contacts with rc motor spray, and it worked.....for about 3 hours. man does that bulb burn hot!!!

it still gets power to the terminals going to the switch, just like before, but no workey.

what gives with this thing? is there a known problem with the material used for the detent ball and the contacts it hits?
