I have an 06 F150 screw and the truck runs beautiful and hasnt ever had serious issues. However, for a week now I keep hearing a random click noise, mostly when Im warming up the truck, while driving, and even after Ive shut it off. Neither the heater nor the a/c is on when this occurs and I havent noticed any difference in drivability or power. Its sounds similar to the fan clutch but the fan clutch wouldnt be clicking after the truck is off. All fuses are good and its really confusing me. Please give me some ideas.
Thank you.
