hello members. im new here and suck at the computer. i have a 93 s10 blazer and cannot get the speedo or signal indicators to work .all the rest of the gauges work. dimmer switch was hot. replaced both headlight and dimmer switch. same thing. any ideas? i think ground but cannot find it. it did work for about 10 min one day. so i am wondering if anyone has had same problem.

 

digital dash, I am guessing bad solder joints on the board, you will have to pull the cluster and go over all the solder joints, quite common with these.

 

thiers a place in ny that specializes in digital dash gm product, cuz my trans am has a digital dash missing the temp sensor, i cant remember at the moment what thier called but gm outsourced to them in the 80s with their dash problems

 

contact this guy. He also does repairs

I got that kit and it fixed my problem in the dash, but your problem is not the power supply. So contact him with your problem, and see what he says.
