Hi Mike.

If the cable is moving freely and is moving the correct lever on the
Heat/fresh air distribution box (the big black box behind dash)
through its' proper travel, then it may be that the foam on the
flap(s) inside the box has deteriorated. i.e. air just blasts past the
flaps.

If you are desperate for a temp fix, if you can find a way to block
the fresh air ram behind grille, above the rad, this should reduce the
amount of air coming into, and out of, the black box.

Hope that helps,

Neil.
