2018 Jeep Wrangler JL Rubicon 3.6L

Recenlty modified a stock tune to change throttle response, and set the PCM up to begin data logging to build a new tune. With that idea in mind removed some of the learning features so I wasn't fighting the PCM making changes as I made changes.

Everything is working perfectly except for the interior fans. When I first start the Jeep in the morning or after it sits for a few minutes the interior blower fans run at a constant speed. It's a fairly low setting and the fan speed will not change.

If I shut the Jeep off and start it right back up the fans run normally.

Any thoughts?
