2013 Tahoe Heater Vents Question
I just recently purchased a 2013 Chevy Tahoe LT and I have noticed something strange while I have the heater on. When the heater is turned on, whether AUTO or MANUAL, here's how the air/heat blows out:
Defrost = comes out of the Dash top vents only
Passenger Vents (or what I call the air conditioning vents) = Heat only comes out of those vents.
Combo (Floor/Defrost) = Comes out of Floor and Front Vents.
Floor = Heat mainly comes out of the Defrost vents and some out of the floor vents.
So, here's the issue, when I have it on FLOOR only, I would say 75% of the heat is coming out of the dash defrost vents and about 25% out of the floor vents. I know some vehicles will blow heat out of the defrost vents to keep the windshield defrosted, but when on Floor it only barely comes out of the bottom vents. I would like to it to ONLY come out of the floor, when I have Floor selected. Dries my eyes out driving...LOL!
Suggestions? Could it be the Blend Door or the Actuator...i.e.?
Thanks!
