No air flows out of any vents. The blower is working. I removed the cabin air filters to see if they were clogged. With those removed the air was blowing strong through their compartment.

i think I have to replace a actuator. I understand there might be more than one. How do I determine which one I should replace?

And how do I find them?
thanks
