Gauge cluster

I have resently added a glow face to my pontiac sunfire and when I reinstalled my gauges my odometer is really dark and it is hard to see! I have tried the dimmer switch too see if that was the problem and that did not work. I was wondering if any one knew why this happened.
Thank You!

Make sure all your connections are properly connected? I beleive the instrument cluster has two connections both on the right hand side of the cluster.

maybe...otherwise maybe the light for the odometer may be burnt out. They have to be replaced from the rear so that would be a good time to check the connections anyway!

Again, I really don't have a clue but these are 2 suggestions
