NO Heat in Mazda 6 2008 2.4
Tried to run the heater for the first time in a year and while all the fans and vents work, there is not heat, no matter what vent or setting. AC works fine. The 2 hoses going to the heater core do not not heat up or even feel like there is any water running though them.
The radiator and the cracked thermostat housing and thermostat were changed several months ago.
So is there a control or climate control valve that sends water to the heater core?
What would you start to look at? Is there perhaps an electrical connection that was not plugged in when the radiator was redone?
Is water running through the heater core all the time or only when the heat is on?
Any Suggestions.
Thanks

I've done a lot of searching and from what I can find it seems that the problem is something called the blend door actuator. The issue I'm running into is that I can't find that part anywhere. Is it called something else for this year and model? Or is there something else I should check. The ac/heat is stuck on face. I can't change to floor or defrost (I turn the ****, but the vents don't switch, though the air type Speed Test settings will change--e.g. recirculated to fresh for defrost).
