Blower Fan Problem

[dwagenseller]

Hello everyone. I was traveling from Ohio to Kansas earlier today and the air coming from my vents stooped blowing. The blower was running because I could hear it and it would ramp up when I increased the speed but no air was coming from the vents. I've replaced the final stage resister two years ago and when I did, the issue was the blower wouldn't work at all and the new part did fix the problem. This issue is different because I could control the speed of the fan but with increased or decreased speed, no air come out from the vents. It was as if something was blocking the air from the blower to my vents. Could this be an actuator issue? If so, does anyone know which one? The backseat blower did work and would blow air.

After writing the above paragraph, I went back out to my X5 and started it up and all the sudden, air is now coming from the vents. Any ideas?

I have a 2001 4.4i X5. Any help would be greatly appreciated.
