I bought 2011 F150 XLT 5.0 six weeks ago and want to know if the a/c in yours cycles on and off. Mine blows ice cold for about 20 seconds and then the a/c clutch shuts off for about 5 second and air temp goes up a few degrees and then the clutch engages again for about 20 seconds. When engaged blows about 31 degrees from duct. Ford says this is normal operations. Any help you provide will be helpful. I drove 2011 F150 loaner and the a/c did the same thing.
