The A/C blower sounds like it should be putting out a lot more air than what is actually coming out of the vents. I am wondering if it could be a baffle problem or loose ductwork. I am going to replace the cabin filter for good measure. Has anyone else had this problem and been able to correct it?

 

Cabin filter would be my first guess....
Lots of gunk ends up there....mice nests, rodent food supplies....leaves, etc...
Possible your fan is getting weak or a bad resistor pack, but always do the simplest first.

 

Yeah. That cabin filter was NASSss-Teeee!
I also ran a shop vac hose up in there while I had it open and also tried to vacuum out all the vents including defrost vents. A little difficult on the A/C vents because they want to close on you when you try to vacuum.
I'm getting pretty good air flow now and its cooling pretry good but I will probably go get the system checked to see if it needs to be charged.
Thanks
