what i mean by this is, sometimes it will work. i will take the bulb out and put it back in and kind of move it around till it turns on, and it will work most of the time allllll day. but then the next day NOTHING! so i have to do the exact same thing every single day! i donnt what the helll is wrong!

 

The switch is probably not making good contact. Also check out the door button (i mean if the light is being finicky while the switch is in the place to turn on when the door is open)

Otherwise, just take it all apart and look. It's a very simple piece of technology =)

 

i had the same trouble in my 94, the switch was very moody, it would just move out of place riding down the road and by my next stop it would be on 'off', it would have to be perfect to make contact, i believe after a while the contacts wear down or it just gets loose, never really looked into it though, just kept pushing it all the way over hah....im sure its probably just a contact issue though

 

could be the switch. you can also very carefully bend the terminals that support the bulb so they put a little more tension on the bulb.
and check the pin switches in the doors- they could be a tad corroded.
