The sauldering on the board behind the lighted display has come loose. You need to get it resauldered by someone who knows instrament panels, or it will do more damage than good.
My 92 Blazer S-10 4x4 lost all the lights on the dash. Local dealership quoted bet. $700 & $900. My mechanic took it out for me ($100), I shipped it to a guy in Canada who repairs these (he charged $125), the my mechanic replaced it. Been working perfectly ever since. I drove the car without the dash with no problem but the remove & replace only took about 4 days anyway. The guy in Canada in online, look up dashboard electrical repair.
I believe that the first digital cluster on a S-10 Blazer was in 1989.
you need a new instrument cluster about $350 same happened to mine.
If nothing on the dash (instrument cluster) is working, I would suspect the electrical plug in back is disconnected.
There is no odometer cable. The cluster is controled by the PCM and is fully electronic. www.trailvoy.com All the answers for your Trailblazer!
Remove the two screws at the top of the instrument cluster. This will allow you to pull out the entire bezel. Pull out the bezel, and pop the switch out from the bezel.
It sounds like a wiring issue. There could be a loose wire on the instrument cluster, on behind the fuse block.
In our 96 Blazer S10, it was behind the radio. We had to remove the radio to get to it.
Fuse panel should be located on the drivers side between the door & the instrument cluster. There is also 3 relay switches located behind the back panel of the glove box.
When my 96 S10's ignition switch went bad my cluster would act "crazy". Needles bounced back and forth while trying to start. It drained my battery and had to jump start. Also ended up replacing the ignition key tumbler twice in it too, but it was the switch down low on the column that made the cluster screwy.
faulty circut board replace it
I would first recommend getting the Chilton manual. I did the heater core on my wife's 96 Blazer. It is a very involved process and should only be attempted if you are a fairly knowledgeable mechanic. You have to remove the instrument cluster and drop the steering column to start. The Chilton manual covers this fairly well. Dennis
its inside the distributor.

You can't. The 4L80E is an electronic computer controlled transmission. The 88 blazer computer will no shift the transmission are even begin to work.
AnswerThe ECM is usually located under the glove box.
it is located behind the ciggeratte lighter. But you have to have the star drivers to be able to get to it
If it is electronic (not cable driven) and both the speedometer and odometer are not working I would suspect the VSS (Vehicle Speed Sensor) is faulty. The VSS can be found on the tail end of the transmission. If only the speedometer doesn't work I would suspect the dash cluster has to be replaced with a new or good used one. Really need to know what year S10 Blazer you have.
I believe in 93 they had the newer style computer, this eliminated the electronic spark control module.
The lights on the odometer on a 1999 Chevy Blazer might not work because of a burned out fuse. They might also not work if the lights are burned out.
The 1997 S10 Blazer has an egr (Exhaust Gas Reclaimer) valve. It also does not have a point distributor, it is electronic.
There is no ECM in the 1985 S10, it is carbourated.
ESC / Electronic Spark Controll Circuit. and the knock sensor signal.
there is a few screw to the front panel where the instuments are,remove them. them there will be a few smaller, I think their 11/32 screw heads,remove them after all that is undione the cluster should move around freely.DONOT PULL HARD ON IT! lower down the steering colomn then reach inbehind and remove necissary wiring and speedo cable. after that reverse the procedure and away you go on the road back to completion.
first check the fuses......maybe the cluster of gauges shorted out?....may need to replace it.
take old one out, insert new one in after you remove the dash cluster.
