On my 2017 REx I noticed the following last week.
When driving in Comfort or Eco and A/C in Auto the car starts off a very nice flow of cool air. Typically I’ll have the fan speed set to 2 or 3. After a few mins the volume shuts way back (even though fan speed is 2 or 3) to almost no air volume at all. I can crank fan speed up to max, but still does not blow much more volume of air. When I hit MAC AC, it blows nice and cold.
Anyone have this issue before?
