Floor Cabin Air Recirculation Car Intake Passenger

It recirculates the kind of cool air that you get from the a c when you first turn it on and the longer it s on the cooler you car gets until it s as cool as the system can possibly be.
Floor cabin air recirculation car intake passenger. I also have a buick enclave 11 an. Half of the cabin air is dumped overboard keeping a continuous flow of air. I have noticed that when i have the air recirculating in the cabin outside air closed off i still am smelling outside air cigarette smoke from the next car while sitting at a light bus exhaust skunk smell. I have a 2014 gmc sierra slt crewcab 2 weeks old.
At the same time air leaves the cabin through return air grills where the cabin meets the floor. The cowl has a channel in it that the glass slides into just above the cabin air intake box. Today i removed the upper cowl cover and installed a rodent screen over the one large air inlet opening on the passenger side which leads to the cabin air filter. Thus the need to leave the cowl in place when replacing the windshield.
The hvac intake system draws from the front cowl black plastic cover in front of windshield down into the hvac housing then thru the cabin air filter to the blower evaporator heating core mode door ducting and finally to the various vents around the car. With all the intake pieces removed one can see the oval opening in the firewall for air to come into the cabin air filter. The seal on the underside of the plastic that is supposed to seal all around that oval opening doesn t so water comes in along the top edge of the seal and builds up until it pours over the lip of the oval opening. Using the recirculation button helps get your car as cool as possible when it s hot outside and you have the a c on.
