2005 E350 problematic HVAC flow issue
Will have my air conditioning or vent on and it is not totally consistent but predominately does happen, all of a sudden all the airflow from the vents will go off, usually going over 60MPH in the van. Then will come back on and the process will continue to happen over and over. Sometimes it is better not accelerating during these times.
Any ideas?

Thank you for anything you can share.
