No dash lights...HELP!

I have a 90 4runner, I know this is the pickup forum but maybe one of you can help me. My dash lights are not working, i have the lights behind all of my secondary switches ie seatbelt, batter, high-beams. The only lights that dont work are the lights behind the speedo and tach. I checked all my fuses and they are fine. I replaced the dimmer switch in the dash. If anyone has any info, greatly appreciated.

Are you sure the bulbs are good?

Well unless all of the bulbs are bad, i looked at them and the fillaments looked good. I then swapped the placement of all the bulbs of the same type, and nothing changed. Ill replace those bulbs and see what heppens. Thnx

Test to see if you are getting power to the sockets.
Check the grounds.

Have you tried the dimmer switch? Every now and then it could be turned all the way to the off postion when the dash is wiped down. I've done that a couple of times myself.
