What have you checked so far? Are the heater hoses hot or cold? What does the temperature gauge show? What year is your van? '91 to '95 models develop sticking temperature doors in the heater box. You can't tell by sliding the lever because the cable has a self-adjusting feature that makes it feel normal when the door is not moving. There's an easy fix for that.
