What can cause the ac not to cool or blow correctly?
Most of the time you're a little low on freon...u can get a gage and a couple cans of freon for about $50 bucks at Oriely's. Make sure you're coolant level is good too....sometimes a low coolant level can cause your AC to cool intermitantly...I've had that problem...and if you can't keep the coolant level where it needs to be without is boiling over, then you have a bad thermostat, that's just a matter of a new thermostat, 4 botls, and a new gasket...hope this helps!

Need to check to see if the blower motor is running.If it is,but not threw the vents,most likely a vent door actuator motor.The actuator motor in this case would be bad,it is hard to get to,unless you are mechanically inclined,You can do it your self.If the blower motor is bad,just replace it.Check fuses first,and the blower relay.If I can help,let me know.

open fuse panel under hood and check the AC Comp fuse. If it blows again you may need a new compressor
