I just pulled a code P1481 and my cooling fan sounds like a jet engine. The code said something about fan speed. It sounds like it is stuck on high. I was wondering if anyone has had this problem. Not sure if it could be a relay or if it is something else. Perhaps the fan clutch that i have heard so much about. My temp gauge has been normal, truck not overheating at all. Please help:duh:
