No air in front vents

[Smooth]

I’m having a problem with the Air flow in my 2004 Yukon Denali from the front vents. When I turn on the fans I don’t feel any air.
Here are some pics.

Probably a blend door issue.

@swathdiver may be able to assist you.

Do you hear the fan running? Does it sound normal? Does the air come out under the windshield or floor instead?

For the front AC, there are two actuators that control the flow of air, the Mode Actuator in the driver's footwell and the Recirc or fresh air actuator behind the dash on the passenger side.

Thanks. I’m going to watch some videos on YouTube and see how to adjust them

UPDATE! I now have heat and ac. It was a part called a blower motor resistor
