Fans running all the time, AC stopped working?

My fans are always running and my AC stopped working around the same time? Any recommendations?

Look to see if the SES is on. If so, the fans will normally be on, too. Flash the code and see what it is.

I flashed the codes, and all I got was 12 over and over. So it's not throwing a code.

Will a bad pressure switch make the fans run the whole time even with the A/C off? Edit: yes it will

Now how do I fix it without fixing the A/C right away? (without programming it out) Any ideas?

According the to factory manual, the a/c pressure switch does not cause a SES light, so I would think the fans should not come on because of it.

Well, I could always replace my cut a/c hose and see if it helps. How do I go about replacing the hose that runs right next to the alernator? It has some type of crimp connectors on the end that connect to the hardline and I'm not so sure about them?
