Ok, so I have an ep3 with a frustrating problem. It seems like no matter which setting I have the air on (vents,floor, defrost,etc) air always blows out of the far left and far right upper vents (driver side and passenger) not as much as when the air is on the vent setting but a good amout, enough so that in order for my defroster to operate efficiently I have to close both side vents to get enough pressure to reach all of the windshield.
I am also having another problem, when I have the air set on the vents, I have very weak pressure blowing out of those two center vents , which I guess isn't that big of a problem but it is still infuriating to me. So I guess I am asking what I should troubleshoot or what would be responsible for directing air flow, if anyone else has had this problem, and if it would be cheap enough to replace to be worth it or not too time consuming to be worth it. Any help or insight is greatly appreciated.

 

Bump for twice as long defrost times

 

try changing out the cabin filter. it might not be a direct fix to your problem but it will free up some airflow for your vents.

 

in my ep3 the air will be off but it lightly blows air like you can barley even notice it>
