All my dash lights are working in my 07 S/C except the odometer light, base cluster. How do I replace the bulb???

 

Remove the 2 screws for the lower dash panel and then the 2 screws for the upper dash panel. There are then 4 screws holding the cluster in that have to be removed as well as 2 wire harnesses. Flip the cluster around and change out the correct bulb. I think it was a #74 bulb.
