Cannot change air from floor to vent or defrost why?

My A/C comes on but does not flow out the vents.

Hello, I'm Danny.

It sounds like you are having a problem with the blend door/re-circulation actuator.It is mounted to the HVAC unit under the dashboard.It's an electrical motor that opens/closes doors to move air throughout the ducts. Here is a tutorial showing what is involved in it's replacement:

The the panel vents on my car are stuck,I can't move them in any direction & the air just blows one way.Can't move them up or down nor side to side.How do I get them loosen or how do I replace them with new ones? If you can help me out,please advise me on what to do & if you know of a video for me to see please let me know.Please get back to me ASAP.

Hi Lesabre15,

It sounds like you have a vacuum line that has broken near the firewall, check this article for more info,

Even though it is for defroster, the process is similar,

Let me know what you find,
