I have an 850 and my AC will blow cold and stop for some reason. I took it to a repair shop and they checked everything and came up with an electrical issue. They said they got the compressor to stop working and figured out there was no power going to it. They worked their way back to the relay and all the way up to the dash. The problem (they said) was the AC control head.
Anyway, I'm looking for a control head! I have NO CLUE where to find one.
Part #: 6849318


Any help?
