Dont think the bulbs can be replaced if you mean the information center. The unit needs to be replaced.
If you mean the lighting for the gauges, then yes, you can remove the gauge cluster and take it apart to replace the bulbs. If there is no lighting for other things like the radio, lock or window switches, etc, then you have a problem int he interior lights diming circuit.
You will need to remove the entire trim around that part of the dash.
A Chilton manula or similar wouldbe helpful because there may be some hidden screws that if you do not remove, you can break the panel.
