Has anyone had this behavior? With the AC set to recirculate and A/C and MAX A/C with fan set to low (1), I’ll be driving down the high way in perfect harmony with my temperature and environment when the fan will pickup and blow harder. The fan still shows it’s on low but the airflow definitely has picked up. It’s almost like fan speed 1 is now blowing at fan speed 2 level and won’t go back to 1. 2018 Expidition Fx4.
