I have a 1995 Mustang, for some reason my instrumental lights (speedometer, heat switches, etc) lights turn off. I swapped the fuses and it worked for a while again, then stopped... I took out the cluster panel and when I replugged it all in it worked good for about an hour then turned off once more. My ABS, engine light, Parking brake light, etc still turn on and headlights, dome lights etc still work.

Any ideas on what the issue causing this may be? My running lights work, just not the cluster lights...
