Default A/C not blowing hard enough

Hello all, I have a 91 Coupe, and the A/C blows really cold air, just very weak air flow though out the vents. And of coarse the the vents closest to the doors air flow is almost nothing. I can hear the fan motor running, and every now and then I can hear the fan squeek for a few seconds. The car sat for about 4 years (so say the PO).
Through researching on the forum I have found that there is no cabin filters on C4, so that's not it.
Any ideas??? Thanks

Does air come out the bottom?

If the vacuum is messed up the system will default to heater mode and all the air will come out the bottom (with a little windshield defrost air).
