You'll need to remove the instrument cluster. First, remove the radio/climate control panel and the lower dash panel. Then you need to pry out the headlight switch, undo some screws that hold the upper dash trim panel, and remove it. This will give access to the four screws that hold the cluster in. Carefully reach behind and undo the two plugs into the rear of the cluster. Remove the cluster and put it down carefully on a clean towel. The bulbs are mounted in twist-to-remove sockets which you can only access from the back of the cluster.

To do this, screws must be removed from the dash panel located around the instrument panel. There are also screws securing the clock adjustment knob and the glass/instrument panel itself. The bulbs twist into the backside of the instrument panel. There are several of them.

It is very hard. You need to remove the entire dash to get to the bulbs. These are maybe not worth replacing unless more than one is out.
