Air leak in passenger floorboard/firewall/intake vent?

I have outside air coming in from the passenger floorboard area but it seems as though that it's coming from higher than the damper/recirculate duct.I have checked the damper, sealed the duct from the insert to the outside fresh air intake and somehow air is still being forced in from somewhere.When the control is on 'fresh' the draft isn't as bad but it increases greatly when it's on recirculate.Im completely baffled and any and all help would be greatly appreciate it ☺

 

Door seal?

 

Door seals are intact and in great shape.My initial thinking was windshield leak or seam but what's stumping me is that the draft has greater intensity on the recirculate position.Its as though it's entering in through the fresh air intake but somehow it's being dispersed before it reaches the fresh/recirculate damper.
