I just got a 2001 Cherokee sport the other day for a mud/rock toy. It has a 12 inch lift on it and runs very good, but none of the gages are working. I have combed the Internet looking for possible solutions and have tried checking every fuse inside and under the hood...none bad. I have pulled the cluster and the two plug in blocks looked nice and shiney when I took the dash apart to check those connections. The idiot lights work...ie back hatch open, engine light, low washer fluid, etc, but no speedo, tach, oil pressure or temp. gage, and no mileage showing either. What should I check next? I don't really wanna start mudding it until I can track the temp. and oil pressure.

Oh, btw, it's only throwing one code, and that's just a loose O2 sensor wire, I'm not too worried about that yet though.

Thanks for any help!
