Another water leak!!!

[crustysarge]

Well after much work and redoing the interior my carpet is still getting wet. Finally got in there and had the wife pour water on the cowl area. Water is coming in around the joint between the floorpan and the kickpanel about halfway up the floorpan by the vent flap.. Looks like there is a seam there and I imagine the caulk/sealant has dried out.

Is this a normal leakage area? Best cure? Remove fenders and seal from the outside?
