Super Newb question about AC
 

Sorry for such a newb question about the AC. Is there a way to recirculate the AC or does it just pull air from the outside? 02 Blazer 4dr 4wd.

I'm not sure if the 2nd gen blazers have the option or not but some cars do have an option that just circulates the air.

Max A/C should flip a flap inside the HVAC housing that block off the outside air and opens up the fan to pull air from the inside...

aaaaah is that what Max A/C does. So when it is turned off the system lets air flow freely from outside?
