The most common problem with heat and a/c in the Ford Windstar is Blend Door failure. The Blend Door actuator on the Ford Windstar can be found by removing the glovebox. A broken blend door actuator is almost as common as a broken blend door itself. Typically, the fix requires disassembling the entire dash and replacing the whole plenum box, which can be a costly repair. Linked here is a video from www.heatertreater.net demonstrating how to access components of the plenum box for repair without disassembling the entire dash.
