I recently noticed that the engine cooling fan has been coming on and off at odd times. in the morning when it's cool it may be on for several miles and then disengage. then may come on again with an ambient temp of 80 degrees. last year in Tampa in august I barley heard it. The two codes in it are po 480 and po 528. The truck is a 2006 F350 super duty diesel. Has anyone else out there had that problem, and could you please advise. Thank you
