^^^ Wash religiously with fresh water (*in situ not removing) to prevent salt buildup
Change every season.
Still don't cook it like you could with an open manual vent as I just had a brand new goretex from the best brand NOT vent at all 
Board hiss in 30deg is not great - thinking about 60 to 80deg in your car hmmmmm
how do you change a Gore-Tex vent?
With care as the cap pops off - so needle nose pliers can be used if you're desperate but get a 16mm thin walled socket. They're only hand tight
edit ok Sunova is an Allen key
Severne too fits it
I installed a goretex plug on an old board. Be careful when you remove the plug. The top plastic is a cap to protect the goretex film and it is not very strong. You want to reach the actual plug that is sitting flush with the insert that is in the board. Don't ask me how I know that ;)
the pic attached is not mine but shows what I am talking about.
^^yup
They go back on OK - ish with a dab of silicone n the lugs but don't get it on the membrane it won't breathe at all
(Biting my tongue about whether most actually do lol)

Don't bite your tongue off; at least half of the goretex vents i have serviced were completely clogged and non-functional.
