The rheostat is what makes your cluster gauge lights brighten and dim by moving the small wheel or it's integrated on your headlight pull switch. I can't remember on the 94 model? It's a ceramic part that has a spring on it and usually the springs get corroded and the lights will come on and off whenever they want.
The problem you might have is finding a new one at a auto parts store due to the age. You might have to try and find a good one at a pick a part. They are not hard to replace.
This is a common problem with the old style lighting.
