At the end of december my dad replaced my heater core and that didn't fix the heater, it still just blowed cold air, so on january 2nd we replaced the temperature blend door actuator and it worked perfectly at all times! so i drove the 900 miles back to school, just as i pulled into the town and started going slower i noticed that the heat got cold. i noticed later that as long as i was going highway speeds the heater would work, but when i dropped my speed, just cold air. now its gotten to the point that even when i go highway speeds the air is always cold. do you think i need to replace the 1 month old door actuator motor or is it something else?
