Somehow, the PO for this GW managed to get a buttload of dead leaf's into the fresh air vent system. I've shop vac'd it several times and more keeps showing up. We don't have these kind of tree's so the channels must be fairly full. What is the best and easiest way to access these vent channels and get them cleaned out once and for all? What is the general consensus about just blocking these vents off permanently? Good idea? Bad idea? Also, does the a/c air routing box with the vents in it, have to be removed? Or is there a silly secret someone knows about?

Simple
Pull the intake grill off the body & JB weld some black aluminum screed available @ home depot. Done without sacrificing anything. I put in a screen & built a scoop to cover the vent no water no leaves done.

If you can't make it better why waste your time. No use repeating the orignal mistakes. I'm to old to push it that's why.

You need to get that crap cleaned out of there or it'll rust badly inside. It's a vent duct behind there with a small hole about 1 1/2 inches long and 1/4 inch wide at the bottom that plugs easily.
One way is to remove the vents grilles from inside the car and reach down (probably about 6 inches) to get all the crap out of there.
Another way is to remove the front fenders and cut an access hole through the duct big enough to fit a spoon through.

I love how arguements end as soon as Ristow comments. Ristow is right...again.

Uh
I don't have any pictures I relocated my washers but I could have built one to go around I bought some lexan scoops off of ebay & modified them to work.
If I had it to do over again I would do 2 of these.
I did 4 of these & cut them to work sideways.\
Interesting I've never seen these. I might have to get these cut them out & out them on the J10.
Now I'm getting carried away but I can see a lot of potential here.
weld & blended into the cowl grill would be cool.

You probably have several skeletons of endangered mouse in that crap. Better not let the People's Republic Of California find out.
Closing off the cowl vents is something I have done with hand made aluminum sheet. I press the sheets into place before a big blizzard, clear the snow off the truck when I need to go somewhere, and routinely leave the covers in place. No windshield squirters. The Defroster can pull air from the footwells though, its reversing the flow direction, but it can work.
The screen idea is great, until wet leaves and crud stick to it and the bits glom onto the fibers of the screen. It will also hamper air flow at higher speeds, though I'm not sure to what extent.
I think the best idea is the first one mentioned -custom cutouts made from magnetic sign material. Just remember to remove it before driving. The other issue with this (and screens) is the icing issue. Moisture and freezing air will stick the vinyl to the cowl. Snow and ice will freeze to the screen and essentially turn it into a nice fiber-reinforced ice-sheet.
Maybe for snowy areas, just pour a gallon of 140 degree tap water down your cowl vent before going anywhere, it melts the snow and ice build up and generally runs out of the drain holes (if they have been cleared by you) before the water can refreeze and block anything up.

A piece of window screen under the cowl grille will prevent leaves from entering. A cheap and effective mod. A scrap of magnetic sign material makes a good cover to keep rain and snow out if you park outside in crap weather.
Pull the grilles and vent doors out from the foot wells ASAP and muck out all the crap in there. Also cheap and standard maintenance task on an FSJ if you want to keep a floor in it.There are 2 rules to success in life...

Duct tape a piece of garden hose to your shop vac and if it is strong enough you will get it all out from the cowl intake. May take many clogs in the hose but it will work. Then take a piece of the aluminum gutter guard from Lowes and cut it to cover the cowl underneath the cowl intake cover. No glue needed. The cover will hold it in place. Works great.Steve

The problem with screens and gutter guards is they collect crap and then you got a really awesome mess to clean out of the screen.

I'd rather clean 1 cowl screen standing up than 2 cowl vent boxes leaning over in the foot wells.There are 2 rules to success in life...
