1999 Jeep Grand Cherokee Question: Why dont I have good air flow from the all vents for the heat and air condition

It is a 1999 jeep grand cherokee limited v8. I have heat and air, but you can not hardly feel the air. you can feel the air if you put your hand about 6/8 inches from ALL vents. If your luck you can feel it on your chin. The dash has been out 2 times replaced the acuators the mechanic said nothing is blocking the flow but IT SOUNDS LIKE A VACUME SWEEPER THAT HAS SOMETHING BLOCKED IN THE HOSE and blows very litte air on high and if you put mid way for the blower you can not feel any air...does anyone know who I can get to fix this my mechanic gave up he said I have to deal with it that nothing is wrong, but when I first bought this car in 2005 the air was great, so I know it will work if only I can find the right person highly trained in my area which is Masontown pa. Any help would be greatly appriciated....Thanks in advance....

    Possible cabin air filter clogged. Suggest getting help to install, it is under the plastic cowl at the bottom of the widnshield. Accessed from under hood.

    NAPA FIL-4903 is the cabin air filter part number for a 1999 Jeep Grand Cherokee!! IF you want to replace the old one. 1998 did not have this part! This one is a bit tricky to find and replace. Ok, just looked, google cabin air filter replace 99 grand cherokee then click on the youtube video. A 1999 Grand Cherokee is used to make the video clip! Good luck with it.
