Message: [QUOTE="xMusclexMikex, post: 1510188, member: 30302"] On my 2012 f-250 powerstroke with single zone climate control, my blend door is not working correctly. When the truck first starts the blend door is getting signal to stay on hot even if my control switch is set to cold. It could be 30 seconds or 20 minutes after the truck starts and the blend door starts working correctly. I have not been able to correlate the time it starts working correctly with any other function in the truck, it seems random. I replaced the blend door actuator but the issue persists. I can actually feel that the blend door is not moving when I move my temp control switch. Then randomly it will start working and I can feel the blend door moving. (I have part of the dash removed to feel this) Once it starts working it does not stop working again until I turn the truck off. It only gets stuck on hot never on cold. I'm thinking either the ac control module or the ac temp sensor but don't want to just throw parts at the truck. Please Help! [/QUOTE]
