i have no air flow through defrost and dashboard vents. how do i fix?
I have pulled most of the dashboard off in order to see the vent doors. it appears that the doors are working. no air coming out the dashboard or defrost vents. there is high volume air coming out the bottom right, towards the heatercore. i believe that one or more actuator motors need replacing. how do i determin witch ones to replace. any help would be grateful. thanks
Here's a basic HVAC flow diagram that might help.
thanks for the diagram. where can i get a print like this in a normal size to be able to read it. (bad eyes)
Click on the print - it will become full screen. Right click on the full size and copy it to your folder. Then click on that "Best answer" button.
