HVAC recirculate air will not stay ON!
So i noticed this, everytime i am about to be in a underground tunnel, i hit the recirculate button, but by the end of the tunnel, i'm sucking in exhaust fumes because it turned itself off.
does anyone have this issue? i have the issue regardless of whether A/C is on. it seems to turn itself off after a few minutes. The feature itself does work, when it is recirculating, i do not smell the exhaust fumes in the car that i am following.
