Mine was slightly melted recently and would only run the fan if you pressed in on the knob. Looks like yours was melted in the same place as mine. I think they 05-06 version of the hvac controls is not available from MOPAR. At least I couldn’t find any. Ended up finding a used panel on eBay. Took the switch off and put onto my control panel.
A panel from an A/C or non-A/C Jeep should work as long as it’s the same style as your year.
