Son in law just bought a beater 1997 LeSabre-- 197,000 miles. Runs good-no dash level HVAC. Blender door actuator is easy to access behind glove box, but even when blender doors are moved manually nothing changes. There is air flow on floor and defrost.
So if it's putting out air, and the blender doors can be moved, why is there no air at dash level? Can't imagine that all duct work would be plugged.
