Hi, I have a Pug Partner '56 plate. Basically there's liquid all in the foot well of the passenger side, when l put the blower on heat with the fans on no heat really comes out, just what looks like steam with a nasty smell... it doesnt demist the windows, infact it makes it a lot worse. Also when l turn the engine off an leave the vehicle, on my return usually my windows have then steamed up just above the heating air vents... the coolant also appears to be lowering in level in the engine bay, which is what could be leaking on to the foot well... I need to replace what l believe is my heating matrix - does anyone know from the description above whether that is correct? Also how hard a job is this to do? Any advice greatly appreciated... Steve
