2014 Dodge Grand Caravan a/c not blowing in front.

2014 Dodge Grand Caravan.  Over the past few months, I noticed that
sometimes when I changed direction of flow of air with the dial knob (dash,
feet, defrost, whatever) it would be slow to react and may take several
seconds up to a minute to change from, say, your feet to the front facing vent.
The speed selector knob worked fine.  Now, the air is not blowing out of any
vents in the front....back works just fine.  If I turn the air speed knob from off to
high a few times, I can feel a slight puff of cold air from the vents but it only
lasts a second or two.  I did remove the cabin air filter and cleaned it out but
that made no difference.  I have heard horror stories about people replacing
the blower motor only to have it fail quickly.  I can't afford taking it to a
dealership to have them try and fix 3 different things.  Help!
