05 Passat, had no heat, both heater core hose are hot, bled heater core by pulling hose and letting fluid come out. Finally pulled glove box and checked to see if blend door was work cable moves back and forth moving door. What I don’t under stand is there is much less air between cold and hot probably half the volume on hot. Finally got it to blow some heat by pulling ac relay. Do I have a blend door problem or is the heater core clogged. How can the core be clogged if both hoses are hot.
