I noticed one day that my fan was staying fully engaged all the time, so I figured my fan clutch was shot. I replaced the clutch however it didn't fix it. My cooling fan stays fully engaged all the time, even in -30°c. So I changed the clutch again, cause maybe it was a bad part. however, I got the same result. anybody know why this could be happening?

Does the A/C compressor come on all the time when you start the truck? If it does, that could be one reason for the constant engagement of the clutch.
