Default No Blower Heat or AC on 2004 Jeep Grand Cherokee

This has long been an issue with my Jeep Grand Cherokee. I have gone through many blower motor resistors, the first one melting in the plenum. The replacement for the OEM design required wiring changes which were made without issue. I have even replaced the blower motor once.

This time, I replaced the blower motor resistor expecting to have a blower again and it did not correct the situation.
Checked the diagnostics on dash controls and it sees no issues. I am getting current to the resistor.

This vehicle is equipped with Automatic Dual climate controls.

Any ideas what else could be causing no blower?
