VENT PROBLEMS

2003 Ford F-150 • V8 2WD Automatic • 252,000 miles

Air only blows out of my windshield vents no matter whether on heat, ac, or just fan. What might this be?

The air flow vents are actuated by vacuum from the engine. Check for leaks under the dash. If you are lucky, you may hear a hissing from the leak with the engine running.
