Recently went on a long trip for vacation. Had a couple instances where AC would stop blowing with much force, but it sounded like blower was still on. Air in vents was cold, just not blowing. Is this some kind of blend or actuator issue? I was able to correct once by shutting off truck for a few minutes. The second time it happened, I turned it off, then to heat and back to cold a couple times. Truck is a 2015 3500 with dual zone AC. Had the driver and passenger side climates synced.
