2013 VW Passat TDI. I barely get any air flow through the vents whether it be AC or Heat. I hear the fans and they are operating correctly. I take the cabin air filter out and it sounds extremely loud like 90% of the air is coming down theough where the cabin air filter sits and the remaining 10% flows through the main dashboard vents. I’ve taken it to the dealership and other auto shops and they say nothing is wrong but there’s clearly something wrong here. Help anyone?
