I would set it to where it actually blows cold. I would disconnect the connector to the actuator and turn the knob to cold. I would then reconnect the actuator and see if that works.

Are you sure they gave you the right actuator. I worked on an Exploorer once that they gave me the wrong one. It looked the same, but aparantly was wired differently. I just happened to notice when I rechecked the part numbers.
