A/C Not Blowing Cold Air...among other things - Toyota Yaris Forums

I know the cooling fan is working because I can hear it turn on and off.

I'm not sure what the thermostat is, and what it does by opening and how it affects the A/C. Can you explain this to me?

Is there anything I should check for physically under the hood? I read somewhere that you can check a pipe coming from the A/C compressor while you have the car running with the A/C on and if you feel the pipe is cold then it should be working right, and if it's not cold then there might be a pressure or freon issue. Anyone know about this?
