Lost strength in driver side vent for feet
does anyone know what the fix is for this issue? basically if i put the heat on MAX level there is significantly more blowing out from the passenger side. driver side vents have very little to no air coming out, and It feels like I completely lost heat coming from the feet vent. I can live without the front facing driver vents, but I love my feet heat vents ! I have read that it could be possibly the Blend Doors motor HVAC ? I have no idea, but I have tried to hold down the defrosts and circulation button and let everything resynch, but still the same issue. Anyone know whats going on and what part I need?

troubleshooting tips...
Your driver side bottom vent no longer works as expected.
Before you start swapping good OEM parts, I'd scan your HVAC module looking for clues as to what's going on.
It may be your blend doors -or the footwell temp sensors -or the controller itself acting up.
Has anyone replaced your cabin air filter lately? There a tiny sensor in there that gets damaged routinely.
