EXT button - what does it do
So we have an "EXT" botton on our cabin air control panel. . when I press it...the outside air temp appears on my display. But, Im wondering if this also lets outside air into cabin and if if does...what is the route and is there a filter?

all it does is display the outside temperature- nothing else
