A/C not working, please help?

My furnace is still working. When I turn the thermostat to cool or just in the on position it will not work. I put the funace in myself last fall. I believe that the wiring and the breakers are all fine. Any ideas?
Update: no it doesn't run in the fan position
yes stat wired correctly
yes, temp set lower than actual temp
no, temp within 10 degrees
not able to test until tomorrow
