That fuse powers more than just the dash lights as the diagram shows. I suspect you have as issue in one of those items causing a short and blowing the fuse as a result. At the lower settings the dimmer absorbs a lot of the current while turning it up causes the failure.
Probably the easiest way to find the problem will be to go to the junction connector 4 at the left side of the dash and unplug it. Then see if the fuse fails. If it does then check the shift bezel light circuit for the short.
The others will be a bit harder to find as you will need a way to measure the current sent into the various circuits.
Does it have the stock radio in it? If not, that could be the problem if it shorted in the radio?
The only other way to test would be to unplug the parts listed and see if the short goes away. Then trace the circuit that causes the fuse to blow.
