Thread: Leaking Dust Seal Back Door Disco 1

So there's a flap/valve that works with the flow through ventilation?

What side is this on? The driver's side OR the cargo lamp side!

Is there a filter too? [Apart from front screen intake]

Its on the drivers side of my 1997 D1. You can get at it by removing the cover that you remove to change tail light bulbs. Mine had popped out of place and there was lots of dust in the area. Its got little rubber flaps that open when you turn the fan on or close a door - gravity closes them when there is no airflow.

I think the only filter is the screen filter. You can get a new one (STL783) for $18.

Refer Post #2.

Do you also run your fan on Fresh Air to slightly pressurise the interior?

No reply to this question as yet. Works for me.

the tubing used in the seals is just some vacuum hose......preferably the soft stuff.....
otherwise it will make it hard (if not impossible) to shut the door.......
if you use anything too thick it will increase the gap further around the seal.......

you could also stick some self adhesive foam/sponge tape to the lip where the seal should seal.....
this is the equivalent of bringing the sealing surface closer to the seal......



as for the flaps......quite a few of the D1s have their vents gaffa taped at the dealers.....(on the inside...!!)
it was the easiest solution to dust coming in through the vents........

same for the range rovers..........
