2007 Tahoe LTZ.
How do I know if my driver or passenger side is faulty, I'm getting COLD air when the HEATER is on, Through my front defroster. Also when AC is off, I get hot air through the front/face vents, on the driver side for sure, not sure if it's the same for passenger side. To the point I have to close the vents so the hot air won't blow on me.
AC works fine.
It's like the blend door is not closing.
Is there a way they can be tested before replaced? They're pretty pricey to just be swapping out, just because.
Thanks
