It appears that there is a bulb in the upper left and the upper right portions of the cluster.

The one on the right side is out on my cluster.

I suppose I can rule out the rheostat on that?

Also, my trip odometer "sticks" at 99.9 miles. It just clicks and clicks but can't get over it to 100.0. It will reset and go back to 0 and is fine for 99.9 miles. Just wondering since it is the same button.
