I got a 1992 Chevy S-10 Blazer, 4.3 L TBI.

My problem is the digital dash is not working entirely. The Tacometer works, the Heat and Oil pressure work. Speedometer, mileage, Gas, Voltage does not work.

I took it apart and tightened the connection up and the gas and the voltage worked for a little while, the speedometer and the gas and voltage work sometimes like it is no getting a good connection.

I got some contact cleaner gonna take it apart tommorow see if I cannot remedy the problem.

The problem lies somewhere with some kind of bad connection... The Dash works entirely...

If anyone has got any tips please let me know appreciated much.

 

Cold solder joints, pretty common. Get a soldering iron and touch them up and good luck. If you don't feel you can do this there is a guy on ebay that does it.
