Why do the dash lights not work in 03 wrangler?

If the dash lights in a 2003 Jeep Wrangler are not working, it could be due to a blown fuse, a faulty dimmer switch, or a burned-out bulb. Check the fuse box for any blown fuses related to the instrument panel lights. Additionally, inspect the dimmer switch to ensure it is functioning properly and adjust it to see if the lights respond. If these components are fine, the problem may lie in the wiring or the instrument cluster itself.
