Speedometer/Tachometer

Hi,
I have an '85 s10 and the speedometer/tachometer do not work.. i'm wondering how i can fix this problem myself because even though i don't follow the speed limit i'd still like to know how fast and far i'm driving.

Replace the gauge clustster.

ok so maybe anyone have a little more info like some details maybe? I can't get my hands on an automotive manual at the moment so anyone able to give me a little less vague directions?

Have you checked all the connections going the gauge cluster to make sure something hasn't fallen off or disconnected?

I would HIGHLY recommend you go to Autozone and buy the Haynes repair manual to aid in your installation.
