I am experiencing the same issue with my 2004 Expedition, A/C works fine, but only comes out of the defrost vent. Has anyone found a solution to this issue. My actuator is out in the back panel as well. Thought maybe that have caused the issue with the A/C in the front.

Any help would be greatly appreciated.

Thanks ;)

I have a similar problem. My ac works fine but when I accelerate the air flow would switch from the front vent to the defrost vent. Idle mode or constant speed (cruise control)works fine. I was told there maybe a leak in vacuum hose. How do I troubleshoot it?
