Ok so here is the skinny.

Over a period of ~3 days my AC went from working to intermittent to nothing. It appears I have different symptoms than most others with the common AC problem.

Blower fan works on all three settings.
Heat/Cool knob appears to work fine. As in it gets hot when I turn the dial clockwise.
AC button lights up and I can actually hear the AC compressor kick in sometimes.
Condenser fan does seem to be working too.
Checked the refrigerant pressure on the low side and it appears to be in spec.

I dont have a tool to check the high pressure side of the system while in operation.

What do you guys think? Could I have a compressor thats gone bad? It stopped working at only 10K miles and since this is the toyota unit I assume its probably not the cause.

You say the AC is "to nothing", but you also say the compressor is working, is that correct? If so, and you have refrigerant, it could be the "flapper" valve that is not closing off the heater. Take off the ducting in the nose where you can see the evaporator and check if the valve is operating.
Cheers,

Thats not too tough to check out. Ill look into it tomorrow thanks.

I would think the heat would be on all the time if that were the problem. I wouldn't say the compressor is working but I can hear the compressor clutch engage. Now if the pump is actually compressing, I dont know. Its possible it kicks off shortly after I turn it on. I dont ever hear it cycle on and off like it used to. The only time I hear the sound is when I push the button.

Check the compressor by firstly making sure it is turning. Start the car, turn on the AC. The pulley on the front of the compressor exists as an outer pulley and an inner hub which turns when an electric clutch is engaged. If the AC is on and the blower is on, but the center of the pulley is not turning, then the compressor's clutch is not engaging. This could be a bad fuse, a wiring problem, a broken AC switch in your dash, or the system could be low on refrigerant (most systems have a low-pressure safety cutout that will disable the compressor if there isn't enough refrigerant in the system).
