Hi everyone, I tried searching to find if there were any other post about this topic but I couldnt find anything. Anyways we just got a 1994 Blazer Tahoe LT edition with the digital dash and when my dad first test drove it the dash all work but then on his way home the dash just went out. The speedometer and odometer still works but everything else is blank. Ive checked all the fuses and they all look fine. Is there anything that I can do to fix it or am I going to have to send it out to get fixed?

 

Welcome to the site.

I once had a '93 Astro van witht eh digital dash that lost everything except speedo. this is going to sound strange, but its true. The fix turned out to be putting some breakfast cereal cardboard behind the dash. My dash was set-up that there are plastic connectors and the instrument panel slides into a preformed case. The connectors are then sandwhiched between the instrument cluster and the case. I cut up some breakfast cereal boxes to fit between the case and the plastic connectors, slide the instrument cluster back in place and it worked for the net 5 years that I had the truck.

 

this is a common problem with the early '90s digital dashes, our '94 jimmy had the exact same problem. i don't know the specifics, but i imagine there are solder joints on the board that break over time and need to be resoldered. if you don't want to dig into it yourself, you can find refurb boards and gauge clusters on ebay.
