2002-2008 Dodge Ram HVAC fan blower not blowing as hard, recirc damper door replacement fixed it

My HVAC blower barely had any air flow coming out of the ducts and I could hear the fan running plenty hard. Here's a video about replacing the Air conditioning / heater blower recirc door / damper that fixed the problem for me. The part number is 902-325 by Dorman and cost about $50 at Autozone.
