I've got a 2005 Explorer - 4.0 6cyl and AT. With one exception, the A/C
works fine. At interstate speed with cruise control on, the airflow will
divert from the dashboard vents to the defroster vents when the vehicle
accelerates, such as climbing a hill. After I peak the hill, the airflow
returns to the dashboard vents. On level stretches of road, or at slower
speeds, everthing is fine. Any thoughts or suggestions? Vacuum leak,
perhaps? If so, how do I begin to find out where the leak is?? Thanks very
much for your help,
~OC~

Vacuum leak, and most likely at the control unit located on the left side of
the engine area looking from the front.
