Leak in Cavity wall

    Hi Just woundering if anyone may have any ideas where i can go with this before i pull down the walls.
    I have a leak dripping down over my two down stairs windows in the cavity. On the outside is stone followed by block followed by 100mm cavity beads and block.
    My prob is i have pulled away the beads up to the damp felt that is running over both windows and have found a hole in both. As i don't want to cut the rest of the felt i have no way of tracking the water the rest of the way up the wall. This is not the one above the windown there is another one further up just below (about a foot) the ceiling for the first
    floor.

    The two windows above are dry no sign of damp or anything..I have sealed all around the windows and cills etc but no joy.
    Not sure how the rain in getting through both the stone and the block to get intot the cavity.
    At the moment the only way i see getting to the source is to remove the stone on the outside which i don't want to do.

    I want to find the source before i go down the route of weather seal as this is only a temp solution.
    Any help please
    :-(
