When I bought the car the gas gauge would not light up so it made the speedo dim but it comes on when it feels like it well I got used of that now my gas,oil,volt,the importent temp (car runs hot) just went out yesterday not to mention the hazerds don't blink but that's not that big of a deal so what can I do to fix the dash? Plz help!!!!!!!!!!!! 86 trans am

 

Since they all have failed at the same time, I would guess it's a fuse. If not you are going to have to remove the dash cluster, it's not that difficult, to check for the connections at the rear.

 

Maybe this thread may be of some help:
