blend door actuator location

If we can step back for just a minute. You are not able to flush the heater core on these vehicles as they are what is called multi passage. What that means is if there is a restriction in the heater core then the coolant will just choose a different path. So if the coolant does this, then the flushing will do the same thing.

So it is unlikely that this is a blend door because this is a cable operated door meaning there is no actuator. I supplied all the info on this for replacing the heater core and the blend door lever. Let us know if you have other questions. Thanks
