AC Freezing up
 

I got a "New to me" 2006 S80, it is a nice car. One problem I am dealing with is that the AC evaporator is freezing up on long trips. It blows great but after an hour or so it freezes up and air will barely blow through it. You have to turn the AC off every 10 minutes or so and just let the fan blow so the ice doesn't form, too much. I am assuming that this is because the compressor isn't cycling off at all. Any suggestions.
