It sounds like you burned a ground trace on the control board (back face of your cluster).
Pull it apart and inspect it. Follow the board traces. It should be pretty easy to see where the break is.
Either repair the trace or look for a replacement on Ebay. I'm not sure if there are aftermarket solutions.
It's worth doing if you already possess and know how to do these kinds of things. Finding a replacement on Ebay or a repair facility will be better if you don't.
Well hopefully i fixed it.. The circuit the fuse was blown on was #15 and was labeled cluster,low engine coolant switch,warning chime, low oil warning relay,air bag diag moduale Noticed the low coolant sensor in the over flow was removed when the previous owner installed a new one. Seen bare wires tapped them up out of the way, replaced fuse this morning before work so far so good!
Now i just need to figure out my charging issue with my 98 GT
If i switch out my cluster in my 98 then i need to do the key and ECM due to the PATS.Glad it was an easy fix. I had a charging issue that I blew 2 months on. You'll never guess it....instrument cluster.
