Air won't blow from face vents in rear. Only blows from floor vent
The rear air won't flow (heat or A/C) from the roof vents in the rear of the van. It blows
from the floor vents from all settings. It will adjust flow based on setting (1, 2, or 3). I
have tried adjusting the vent setting from the front controls and from the rear controls.
Neither will make it blow from the ceiling vents.
Maybe clogged with something or vent doors inside somewhere not moving and in closed position
