While your post is not completely clear, I’d suggest checking the instrument panel dimmer for proper functioning. ---

The dash in your car is one large electronic module. It is 34 years old and likely has a failure of several components. It might be a fault in the control that varies the brightness of your interior lights if those also have a problem. If that control is OK, then you are in for some serious internet searching to find a company that can repair this part.
