where is the blend door actuator located ?

What is your question?

my wifes car the 2008 jetta ive diagnosed the blend door actuator is bad the heat is on constantly even with the temp control at its lowest setting is the actuator and blend door above the blower motor do you think the temp control is bad too or if I get that door shut properly it will fix the problem ? We had a heat index of 104 today so it would be nice have the heater off and not pay some mechanic 100 bucks an hr. to fix it
