hi my name is ***** ***** will be helping you today
so the blend door you are moving when you move it do your hear any change in sound air movement at all
so if you are shore you have the blend door for temp then the heater box is broken inside and the heater box will need to be replaced the blend door directs air threw the heater core or the a/c condenser by blocking off one of them so if it won't change at all it is broke off on the inside. its a big job have to remove the dash board to change it
