    Pop the hood and run the A/C. Check that the A/C compressor is spinning. If it is, buy a recharge kit that comes with a pressure gauge and hook it up. Juice it up if its low and check again.

    Blower motor failure is fairly common and has nothing to do with your compressor. However you CAN destroy your compressor by running the a/c without airflow across your evaporator (cooling) coil. The blower is accessable behind the glove compartment. Remove the assembly and check the bearings by attempting to spin the blower wheel. If it won't move or spins only for a short time and stops, your bearings are bad. Also, you can check resistance across the motor windings with a multimeter to see if you have a shunted or grounded motor.

    If your blower is bad, this advice will destroy your compressor. Overcharging a system without a leak is also a very bad idea, as you add refrigerant you increase your system pressure, lowering superheat and minimizing cooling efficiency compounded by overworking the compressor. It makes a simple fix a very expensive one.

    Just gonna run it up to the dealer early tomorrow morning. I haven't used the AC at all just running the blower for air which isn't working now. I'm hoping that whatever it is is an easy fix and is under the extended warrenty as i'm at 45K right now. Thanks

    You can run to dealer or if you want to check if blades are stuck you can remove in cabin filter and try to move your blower blades (do that with blower in OFF position )

    You don't really care, do you.
    I had this problem with a dirty cabin filter in my '06. Just pop the glove box and pull out the filter and check the blower motor fan. Mine had palo verde and mesquite needles all in it and as soon as I cleaned that junk out it fired right up. I find that my blower motor fan gets stopped up pretty easy if stuff gets in it. I'm surprised that I got so much junk in it with the cabin filter perfectly in place, but maybe one of the times I was cleaning/replacing the filter I must have knocked some junk in there. Now I check it all the time and keep it clean because it only takes 2 minutes.

    The filter is there to protect the cooling coil from all of that junk, not the blower. With no filter that stuff along with dirt and dust would clog the coil, restrict airflow and cause your a/c to fail. It's not to clean the air for YOU necessarily as it is to protect the efficiency of your system.
