closing pressure things

[Ricky A.]

so theres these 1 way valve things on my truck to relieve pressure when u close the doors. but they rattle like hell. can i close em off or will i pop the seal on my windshield when i slam my door lol

The cab won't be totally air tight even with those things sealed. There's still plenty of ventilation.

Think about how much spl it takes to blow out a windshield, then think how much pressure the door makes when you shut it.

You'll be fine. Seal 'em up.
