Harpic

Good evening Nissan owners, I'm new here but would like to ask a question, I have a Pathfinder which is leaking coolant from the heater matrix, it's a 2011 Tekna model, does the dash have to come out for repair to the matrix, the reason I think it's the heater matrix is I have coolant dripping out of a vent by my left foot, thanks, all help appreciated
