The lights were not working in the instrument cluster so I decided to take it off. Well the bulbs are good but the circuit board thing is completely rusted away. It looks like it comes off but I have no idea how I would find a new one. Any ideas how to repair or replace this?

Its an 1988 S10 2.5 with 5 speed manual.


Edit : Found the only one available on Ebay for $55. It says its for an 86 but looks identical to my 88. I will update when. It comes in and try to swap it out.

I believe this is from the windshield leaking down on the dash and dripping directly onto the cluster.

There are companies that make replacement printed circuit boards for older vehicles, I don't know offhand if any of them make one for s10 instrument clusters. If you can find a new printed circuit, it would be an easy thing to swap out and that would be the best option, imo. Just google 1988 s10 IP printed circuit and see what comes up.

I purchased the only one I could find on ebay. It was $55 and looks to be the identical one for my instrument cluster. It says its for an 86-87 but everything looks the same as my 88. Will update when it comes in and I swap it out.

I couldn't find a new one and found 1 used one on ebay that hopefully works.

You should be ok with ‘86 up to I believe ‘90. I think ‘91 was the change over year to the different style like my ‘94.

Check out Facebook Marketplace too. I've had a ton of luck locating NOS parts for my '89. Also, there are aftermarket companies that make replacement kits. They are not cheap though. Also, I would recommend buying this book. I'm restoring my truck now and it's been a lifesaver. You can find it cheaper if you look though.

Good idea about Facebook. I have access to ProDemand since we buy it for work so I have all the manuals and guides on my PC.

I just pulled one from my local junk yard. Ended up making a new cluster altogether. Looks better in my opinion and nkt perfect but definitely better then the stock one.

Wow that does look good! Is there a guide on how to do that? My local junk yards do not have much left of first gen S10s. I found a PCB on ebay though.

No guide just some trial and error lol. What i did it found the pinout diagram online and then made a harness with plug, in case i need to remove it, then took piece of cardboard made template and then fiberglassed that to factory cluster to strengthen it. Bought everything off jegs. Key is to find the right gauge based on resistance. Had to get an adapter for speed cable. Wasn't a hard job just allot of planning and patience
Top pic was original design but wouldn't fit so moved 2 small ones to A piller.

Thanks. Re-did it since had previously replaced cluster and then had problems later that year. Turn out ground for deiver front light was bad. Fixed it and never had a problem. Issue we had was when you signaled high beams would flash so i assumed it was the ribbon cable since it was delaminatung
