I have a 92 blaze 4.3 tbi 4x4. The cluster is dead so i took it out and took to a cluster fix guy that has pretty reputable work, he had it for less then a day said he plugged it in and it worked fine, he even put it thru its paces and left it on for 4 hours and never had even a dim or anything go wrong with it luckly he didnt charge me.

So now it something in my rig ( btw the cluster didnt work when i bought it two months ago so i have no idea when or how it died). Now i get the fun job of tracing wires and fuses.

Two things:

1. Does any one have a pin diagram for the plug that goes into the back of the cluster.

2. Any suggestions on where to start, like a common problem area or something along those lines.

Thanks, love this site has saved my butt more then a few times.

 

start with the grounds, the main one for the cluster is located under the dash above the parking brake. could be loose or have completely came of

 

Thanks for the tip! Wasnt it tho two fuses were blown one for the horn one for the brake (thats what it said) sure wish i would have checked those before i ripped the dash out lol
