Instrument Cluster

[Red007]

Afternoon,

I have a 96 Chevy C1500 V6 4.3 Cheyenne. I recently pulled the cluster and changed bulbs and put it all back together and now most of my gauges are reading wrong. I have looked around on the web and haven't found anything very useful except for the fact that most are saying to just pull one from a Junkyard and then throw my old one out. Any help would be great thx

I would suggest going back in and making sure everything is connected properly. A loose ground will mess them up.

Those had pretty flimsy circuit laminates on the back of them. If you clean the printed contacts, you may well solve your problem... if they were all working before your fix.

I think 94 and older were the ones with those flimsy "ribbon type" circuit boards, but I may be wrong. But as far as your problem, try putting the stock bulbs back in and see if that gets rid of the problem. If it does, then that tells you that at least one of the bulbs is causing the problem, most likely by being defective and causing a short or grounding out something on the circuit board. So if it DOES work fine with the stock bulbs, try putting the LEDs back in, but one at a time. And check it again before plugging in the next LED bulb. That way you can narrow it down to one single defective bulb if that's what the problem is.
