My 2011 F250 the ac comes on full blast, not at all, or is controlled by the switches. It has a mind of it's own. No rhyme or reason. It blows full blast and I have to turn the vents away because it will not shut off. Then it doesn't blow at all no matter what the temp is set at. It is possessed. A buddy said he had a similar problem but doesn't know the name of the part that needs to be changed. He said it was easy. Any ideas?


Thanks,
John T
