2007 Edge SE with manual controls/adjustment with heat/cooling.
A few weeks ago I noticed nearly no air passing thru the floor vents when the vent selection is on the dashboard/floor position, and while the temp selection is on the hot/heat area...Now when I turn the knob to the cool area - there's plenty of air moving thru the floor vents while still on the dashboard/floor position.
There's also a noticeable loud fan blowing in the dash while in the warm setting - however this goes away when the knob is adjusted to the cool zone.
There's no other issues with ventilation (as of yet); all other floor combos (floor alone, windshield/floor) work just fine with both cold, and warm air.
The dealer service advisor had a technician look into it; they claim a few other 2007 Edges on the lot do the same thing so there's no problem <_< - however I recall that this wasn't the case this past spring when there was good air movement thru the floor vent while in the dash/floor setting.
2 months ago I had my radiator coolant flushed; also got the letter in the mail concerning corrosion.
Any ideas?
