I changed my thermostat now only hot air comes out. I checked and checked the colors of wires and made sure they are in the right spot. Every time I turn it to cool it blows heat (heat that smells like heat).
Please help it's hot!

You need to take a second or third look at the wireing diagram,,
Did you tag or mark each tstat wire as you was taking them off the old tstat
Since you didn`t say have to guess that you are dealing with a heatpump, and since you didn`t tell us we have no idea what kind of tstat you are trying to hook up
