I have a 2008 E250 and when I turn the AC on high or low the blower sounds right but there is barely any air coming out of the vents. I read where they do not have a cabin filter.
Couldn't find any info on where it is located. But Ford does like to put them below the windshield on some models like in this video. https://www.youtube.com/watch?v=pLGtPdttI8Q
