Odometer light help

I have a 2001 cavalier and the odometer light is burned out but the rest of the lights work but I am not sure how to replace the lamp. I pulled the instrument cluster out and I can take the back off because it has clips to pull off and it exposes the circuit board. I can look inside and see some lamps but it looks like the odometer light is not accessible. How do I take off the circuit board to get to the odometer lamp and replace it, and is this the way I am suppose to do it? Any help with this will be greatly appreciated.
