a/c changes when driving

Asked by Sep 16, 2012 at 02:23 PM about the Ford E-150

Question type: Maintenance & Repair

A/C blows from dash in park no problem. But, while driving up an incline for example, the air will blow from other vents, winshield then floor and back to dash once the speed has leveled off. I think its a vac leak but not sure where to look. Any help would be appreciated.
