blower fan
Could be something as simple as the screw on the squirl cage is loose and not turning the cage. Just an idea. To check just pull the blower motor and see. You will also be able to see if the motor is turning at faster rpm'*. Those plastic cages tend to crack at the shaft of the blower motor.

Pulling the blower controller will allow you to see a sizeable area of the evaporator core, and what I suspect you'll find is that its fins are oily and clogged with dirt. Cleaning that will improve the airflow, per the TechInfo article.
Ideally, replacing the evaporator core is the main fix (since it probably sprang a leak, the source of the oily mess), but that requires a lot of disassembly.

My goof, Andy, I thought she said it DID sound like it sped up. I agree with checking the voltages first.
My evap core, however, didn't spring a leak, but was clogged with dust/debris. I increased my airflow by about 1/3 by cleaning it. Jseabert gained about 50%.

Somewhere around here I still have the photos from last summer'* big evaporator core replacement project. Gotta write that up sometime...
BTW, are we still unable to embed photos in TechInfo articles? Seems kind of weird that we can't, what with all the images getting plastered all over the regular postings here...
