Anyone having problems with their heating/cooling system?
I have an '06 350 6.0L. Yesterday I noticed that my fan is "stuck" on high while the truck is running. It doesn't matter which outlet it is directed through (floor/dash/defroster) or even whether or not the heater/AC is on. I checked the fuse and it is fine. If I remove it, it does turn the fan off. Couldn't find any mention of this problem by searching. Anyone have any ideas. Any help would be appreciated.

For the fan to be on high when the key is on, there is a short supplying switched power to the fan motor. If your truck is stock and no one's fooled around near the fan, I'd suspect your a/c fan switch is fragged.
