I have a 1995 Impala SS and my digital speedometer has been going on and off while Im driving for the past couple months, I dont know whats causing. But in the last week it has completely not worked at all to where it usually goes on and off within a day or two max. Also along with that my gauge lights went out, the ones that I can see my fuel, oil pressure and battery information. They all work just no lights so I cant see them in the dark. Any ideas on how to fix these? I cant afford a whole new cause they look pretty pricey so any help would be much appreciated. Thanks.
