I'm looking for a good way to free up my distrubtion flaps, and have found reference to putting a self tapping screw in the heater box "somewhere", but does anyone have a ref or pic? Seems the definitive guide was on rr.net once upon a time, all i get is dead links, but maybe someone here has actually done it?
It's here https://www.rangerovers.net/threads/photos-of-method-for-freeing-blend-flaps-with-s-t-screw.14322/page-2. What you are doing is removing a clip that holds the two sides together and putting a self tapper in to keep them apart slightly. Might be worth putting some RTV over the holes and gap once you've done it.
Tnx Richard. It's not the most elegant fix in the world, but it definitely works...amazing
