Could have a bad voltage limiter on the cluster, what year ? I will look at the wiring diagrams and see.
I just changed my dash lights to white LED bulbs...huge change..much brighter.
If you go this route, you can't use them in your two dash signals, just keep the old ones in there.

Which LEDs did you use? What size? Where did you buy them? TIA
These are the ones I bought for the dash;

I bought all the bulbs from this guy...shipping was free and quite quick.

Make sure they are the right ones you need, the ones I ordered were for a 65 Dodge. They sell kinds.
