Dust in cabin

Recirculate to pressureize the cabin.

I would say it'd depend on whether you're following other vehicle/s which are kicking up dust. I always leave my air vent on fresh and switch to recirculate when an oncoming vehicle is coming towards me on a dusty road. When I'm in a convoy on a dusty track, I make a point of hanging back far enough to stay out of the dust; always thinking that whatever dust is coming in the cabin is also going into the aircleaner (not good).

Hi

was told by a local Mazda dealer that their new cars let in a small percentage of fresh air even when on recirc. Not sure

. when this started happening
. if it applies to 4wds
. if other makes do this as well

Suspect hilux's do this based on experience on the cape.

I use recirc that seems to work just fine!

But the trick I picked up was to put Blu-Tac on the drainage holes under all your doors (external to the rubber seal) to stop any entry of dust in the door cavity and subsequently the cabin through all the door bits and pieces!

This really works but just remember to remove the Blu-Tac when it rains or you'll end up with a door full of water - the slish slosh when you open or close the door should prompt you if you forget to remove it.

That happened to me once when it rained while bush and I emptied a fair bit of water from all the doors. If that much water can get in thru the window seals, how much "airborne" dust can get in thru the drainage holes (which are in the most dusty environment) and then empty into the cabin? Give it a go!

It would be interesting to see the results from somebody testing both scenarios under the same conditions. I'm of the opinion that having the vent selected to fresh will pressurise the cabin slightly alright ......... with dusty air.
