Someone had attached the port 5 on the diagram Hose to a bolt on the air flow meter, I couldn’t believe it , confused the hell out of me . But it seems your info was correct. Thanks for your help gstuart

Does your fresh-air flap work ok now?
Been checking out my own system since being unable to coax much warm air out of the heater/demister the other morning when it was damn cold early on, even with the fan on. Checked out the both the rubber pipes in the engine bay today, large one still on the plenum cover & no splits in either rubber. Not wanting to run a cold engine I detached the plenum end & put it into a vac. nozzle & stuffed rag around it on the assumption that the vac. would at least suck as much as the plenum connection. I think the switch is working as a faint click can be heard when the lever is moved (with the ign. on of course) but the bottom flap doesn't move. This flap is currently open (hoping it stays that way when the engine is started) but the footwell / screen vent flap is internal & obviously controlled manually as the lower flap doesn't move as the air-flow changes direction when selected by the RH lever. 'Oh why couldn't LR have left things as they were

I’m replacing all vac lines for the heater and cruise control , the RR is still stripped out so and I haven’t started it yet but I had a mate suck on the pipe coming from heater control (he went purple ) , I can hear something happening so that’s a good sign. I’ll have a look later to see what aspects are mechanically controlled and which are vac controlled.

I don't have the advantage of a stripped out car so the engine bay is mucky to work in, but then I don't have the complication of cruise.
Just a thought, if the vac unit IS faulty (or even if the pipes' become detached under the dash) would that effect the engines' running, after all the 'ball' is only getting it's suction from the intake trumpets within the plenum cover?
Also, if the stupid system continues to play up (as it's done consistently for the last ten years) it can't be beyond the wit of man to fashion a manual control for the bottom flap & with the tiny amount of driving in heavy traffic I do I don't really need to recirculate the air/heat.

You will find this useful I expect

Thanks for that, but what model year is your RRC as the image doesn't seem the same as what I see when peering either side of the trans. tunnel. The footwell air/heat outlet is one large flap, then the airflow is directed sideways by the shape of the lower dash.
