Ok totally new to the forums. I'm new to Cherokees as well but compitant mechanic. So was pullin the dash to replace a broken heater box. Pulled the a/c out while I had it apart and all the coolent lines as well. Got everything put back together and no power to the guage cluster and no start. Got everything all plugged back in. Checked my fuses and the block connector on the inside fuse panel with the bolt holdin it in was melted. So cut and spliced in a new on and a new fuse panel as well. All connections are good. I'm lost.
