Russell,
Nissan are helpless, you can adjust it to the point where it does not leak.
They also have a problem whereby the bottom latch disengages.
There is also a fix from Nissan whereby the change all the seals.
I personally adjusted mine as it used to pop open and it is now OK, no dust and does not pop up, does not squeek.
It is quite tricky to adjust properly...but Nissan employs all aprentices!!!

Hi Russell,
I have a new Jackaroo and the dust comes up the drain holes in the rear doors and through the door trim any were it can.The dust also comes in through the rear door seals sometimes. I am told this is common for barn style doors.I know I wasen't told this before I brought the car.
Good Luck!

Geoff

Nissan put a kit in mine after a lot of complaining. Just crossed the Simpson and it did not seem to make much difference. We did not get too much in but it was enough to be a nuisance. Also you really have to slam that back door!!!

Nissan had a kit of new seasl for the early models, the seals should have been standard on 1999 onward vehicles. I get a bit of dust which catches in the top door seal and spills in when you open the door. You can get a dust deflector from Nissan (and possibly other sources) which will help to keep the top seal clean and reduce the dust ingress. And I also have to slam the rear door very hard, plus it squeaks a lot with the 285 mud tyres on.
