Our 03 Durango HVAC system doesnt blow much volume at all, blows cold or hot as desired but not much force, even though the fan sounds like its going a 100 mph. I know theres no cabin filter to get plugged up, searched that. No luck on where the intake is to see if its got garbage blocking it or whatever. Any help or direction is appreciated, thanks.

 

The air intake in behind the grill looking area on the wiper cowl.
