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
