Howdy Folks, I am in the process of Dynamatting the doors of my new Ranger. I have cut a piece of plexiglass and installed over the access panel, as shown in the pic below. I am ready to apply Dynamat to the outside of the door now, but I wonder if I can cover up that air vent?

The vent is easily removed and I could put plexiglass over it too and cover it with Dynamat. But I don't want to cover it up if it has a needed function.

Does anyone know what this vent does and if I should cover it or not?

Thanks!



I saw Korey's How-to on sound dampening and it was left uncovered, but no explanation was given. :)

 

Perhaps it's a way for air to get out, to balance the air being forced in by the fan.

 

Probably meant as a way for air to escape when closing the door. It relieves the pressure so the door will close properly. Either that or I'm wrong, but I wouldn't cover it.

 

i'd say its just for airflow. i know the superdutys have vents on the rear of the cab.

otherwise the fan would keep blowing air until your cab until it explodes.

 

its a pressure vent...keep it

 

Are you gonna do another how-to on sound dampning?? Looks like you're doin a good job

 

I think you are right, smash lizard. I'd probably get it sealed and then not be able to close my door!

Yes, I had not thought about it before, but the flap is on the internal side of the door and can open only outwards. So, yes! As the door is closed, the flap must open and that is probably the only time it moves. Thanks for your help.

 

What about letting air in to dry the water that gets in there?

 

OMG! Please, no, I've hardly put any miles on yet! Hahaha.

I for sure won't cover it!

 

Yes, thanks morris. I now have several good reasons now not to seal the vent. Yeah, every time the door is opened and shut, the inside gets fresh air.

Probably void my warranty to cover the thing too! Eeek!

 

Yeah don't seal it up, it is a pressure vent. Otherwise the door won't shut
