A/C pushing air in ducts but out vents
Bizarre problem here.
New ‘21 Avalanche 5er.
Vert covers on: very little airflow out-just enough to move a strip of paper.
Vent covers off: more air discharged and will move the paper strip a little more.
Stick your hand up into the ductwork and there is tons of airflow. We taped an envelope partially into the vent area to “block/siphon” some of the air movement and we start getting a decent amount of air-flow down into the rv.
Is there a “block” missing in the ductwork that forces the air out the vents?
