Looks like the temperature sensor stopped working. It's probably in some kind of safe-mode, where it won't let you run the A/C. I'd guess the radiator fans are running constantly as well. It is probably also running very rich (as if the engine where extremely cold), so you'll want to take care of this as soon as possible.
