A/C wont change from defrost
I have a 2005 ford excursion limited, 4X4 diesel. When I turn the A/C on it will only blow through the defrost vents (windshield and front windows). I push the other buttons to change the flow and get no response. I hear there is a vacuum actuater under the dash, any ideas

You have a vacuum leak (95% likely) or a bad air blender (5% likely) Most common spots for vacuum leaks #1 somewhere in the 4WD lines. #2 whatever lines are exposed to the most heat or vibration. That may sound like generic advice but that's how it is, vacuum leaks are tied for the most irratating problem to figure out, oh yeah, electrical gremlins are the other tough one.
