There are 3 vents next to the windshield that blow and there are 2 vents closer to driver that do nothing. You can open them or close them. One way if to recirculating air from inside the cab and the other way is I think from the outside air coming in. Im not sure if I should close one and open the other or close both or leave both open for coldest thanks
