Hooray !! The ANSWER !!
The attached picture shows the passenger-side under-the-glovebox view of my 2014 (actually manufactured Nov. 2013) Journey / front-wheel-drive / 6 cylinder Dodge.
I did finally go to the dealer and the parts-guy even pulled up the same info as everyone else.
When I showed him the pic .... and that I'd come across one other person with the same issue (but no solution as well).... he started clicking around the diagram in the parts-view of the Dodge factory parts software (each component illustrated is click-able and additional information will appear).
Clicking the resistor that is commonly mounted in the space brought up a statement that "in some models, entire blower-fan assembly replacement is required". I can't remember if that was the exact wording.... but it was something similarly vague (i.e. does that mean the blower-fan has to be replaced ALONG WITH a separate resistor mounted somewhere else....etc ?)
It did not simply state that the resistor component was integrated or built in to the blower-fan motor itself. However, he did provide a part number, but noted that it was on back-order, and even then, couldn't make any guarantees that it would be the one for my particular model.
Anyways..... I wrote down that # and started calling around. Fortunately, 1 of the regular parts places (that you'd all recognize) just happen to have ONE in stock. It cost about $175.00. It was available from on-line sources for much less, but I had to have it same day.
I don't still have the OEM Dodge part#, but the equivalent Duralast part# that I used is: PM4093.
I have no idea how someone can otherwise know if their model is one of these exceptions (no separately replaceable resistor) without just looking. It's puzzling...and disappointing that in this day-and-age the software that all these parts places use doesn't clearly state this and have it come up in the potential parts list whenever someone goes to ask / search.
And...after all that, it was an exact fit and was just a quick bolt-off / bolt-on replacement. The whole process would only take about 10 minutes (or less) ...... IF THE STUPID PARTS SEARCHES WOULD JUST INCLUDE THIS EXCEPTION !!!!
Anyways, mystery solved. Hope this is of some help to others in the same situation.
