Could honestly be a multitude of things. Make sure that the condenser fan is working. (On the driver's side of the grill there's a second "radiator" with a fan. That's the condenser and condenser fan.) If that fan isn't working, you'll overheat the A/C system and will not get cold air unless you are moving. The high temp switch could be faulty, but not usually. Or the system could be low on freon, which would indicate that you have a leak somewhere. Not good. The light flashing on the dash could also mean that the control head is malfunctioning. I'll dig around and see what I can find.
