Louie, I have the same problem in same locations in my 14 JKU. For reasons unknown, if the fan is not running, I get very warm air, to the point of being uncomfortable in the front foot area wells. Seems like airflow from the engine bay is somehow vented directly into the front cabin area. I'm sure the tranny and xfer case fluid levels are good as I had both changed recently (problem was present before the services were done).
