What size fuse? I'm missing something, fuses ain't spossed to "light up". If they are, they should blow. If they are, there is a dead short somewhere in the turn signal circuit.

I'm going to say it has something to do with the cluster being wired differently between the two years. Unplug the connection on the back and see what happens then. Obviously none of the gauges will work but i bet your fuses don't light up anymore (they should never "light" up unless they're about to blow).

what i mean is when i turn the key to the on postion i check the fuses one by one with a test light the test light lights on each fuse.When i put the turn signal on the test light,the light get dimmer then brighter sorry about confusing you

Use a jumper from the ground on the instrument cluster to a known chassis ground.

I had a dodge van that one day started doing something similar,the dash lights would flash with the blinker,left turn lit up the rights etc, turned out to be a bad turn switch in the steering column.
