HI, I had starting problems with my jeep. I cleaned the corroded wires to battery and replace the battery terminal clamps. The jeep started up just fine. Shortly after a test drive the instrument panel stopped working. Only had lights and symbol displays. I removed and checked instrument panel tracings-good. I checked all fuses-good. I tried removing cables from the battery to try to reset computer-nothing. Any help or sugestions will be greatly appreciated. Bryan

You might have shorted something out removing the battery wires, check for voltage somewhere behind the cluster?

I'm having the same issue. But mine is intermittent, it works for a while and then it stops working. The gauges stop working but all the cluster warning lights come on solid.
If anyone has found a fix for this type of issue, please share.
