Your cars AC unit re-uses the air in your car instead of pulling new air from outside.
@Gruncle Stan, I only use it if I know I'm about to pass a farm or dead animal
@MeddlingKid, Or New Jersey as a whole...
@bowlnmike, or if you rip a monster fart and you are mad at the people in the car with you
@MeddlingKid, it's really good for hot boxing
@MeddlingKid, i know, right? But it's actually designed to cool more/faster by cooling air which has already been cooled
@I Am Captain Obvious, I know this is a very dorky thing to say, but I feel like that can't be good for your air filters
@MeddlingKid, you're probably right, but sacrifices must be made
@Hallucinated corpse, I've thought about that, but it gets stuffy
@MeddlingKid, or you see the truck a bit in front of you accelerate and jet-black smoke shoots out
@MeddlingKid, should use it all the time, you'll get better gas mileage. The less pull on the engine the compressor does, the better
@MeddlingKid, a guy once walked in front of my car and a moment later I could smell fart...... I'm sure that guy farted and my car sucked it up and served it to me chilled
@MeddlingKid, great, now I have the smell of a field of diarrhetic cows and dead skunk recirculating in my car
@MeddlingKid, most cars don’t have filters
@Hot Coffee, every car i have ever owned has had a cabin air filter
It’s the anti JFK device. Keeps you from getting shot by someone on a grassy knoll.
It keeps the air inside so your car can float.
Ahhh, must be vaccinated to be that retarded
Recirculates the air in your car instead of pulling in fresh air from outside.
I use it when it's really hot and I'm using the AC or when something stanks outside.
Remember to Not use this at least sometimes so that fresh air can clear out some of the stank from your car and your ducts.
Its rewind time
All i knew was that it made my car cool down alot faster.
i also have a nissan
