Which actuator is it??

[Jack W]

Now the damn temp blend door only works half the time. Ready to throw in the towel. Gonna give the shop another crack and change the temp blend door actuator again. Which one is it? There's two behind the radio and another behind the glove box. Is it the one on the back of the HVAC box? If it's one I can get to that'll save me some money. Any help?

2 actuators behind the radio bezel
1 actuator just to the left of the Fan
1 actuator straight up from the fan

some HVAC systems have another actuator hidden between the HVAC box & the firewall, i read about 5 actuators being in the Mega cabs for one.
