Anyone know a current source for these? I was looking a few months ago since the rubber flappers in mine are all shot and they were still available, but everything now shows out of stock. Trying to cut down on the amount of dust that makes its way inside the back door when I'm off-roading in the desert SW.

 

Maybe HUMMERZ will sell you his.

 

That's how the air gets IN, not OUT.

Exactly! They are found on every single vehicle made/sold, at least in America. It is part of obscure Federal requirements for ventilation. They can usually be found behind the rear bumper end cap on most vehicles.

 

Air flows in multiple directions!

 

 

maybe you an come across a dryer vent in the size you need. many have shutter doors on them.

Buy yourself a rubber sheet: https://www.mcmaster.com/products/rubber-sheets/ Cut out a square the size of the vent. make some 3 sided cutouts for the flaps so they'll flex out when under pressure and close to keep bugs/dirt out when not under pressure. Project complete.

 

Excellent vent, I installed 1 during my reno. Clothes dry faster in my Maytag after replacing the 70's flapper vent.

 

Check that out! Hummerz' truck is AWD, and so is his lawn mower!

 

10yrs old and still works great. However, my new home has a huge grade down the sides and to the back. I recently added a 6 Speed, now easier/faster for me to cut the lawn. My wife doesn't like the YM, so I have to keep the CM. After 40yrs together, I know what to do!(She-shed)
