This is an odd one for sure. 2011 full size range 139,000 miles. My personal truck. After a long drive the A/C HVAC airflow stops coming out of vents but you can still feel the cool a/c air slightly. No faults get stored when checking with SDD and if the vehicle is left to "shut down" for an hour or so its back to normal. No amount of fiddling with the controls cures it when it's happening. Because of the odd nature of this I'm leaning towards a HVAC module but I wanted to now if anyone has run across this, as in my shop this hasn't been seen before.
well thanks ahead of time!
