So the temperature has started to drop and I have recently developed a whining noise under the hood. It is related to the rpm's. It does it when driving and when stopped. I believe it is coming from something being run by the serpentine belt.
I tried turning the steering wheel back and forth and the pitch of the noise did not change, so I don't think it is the steering pump.
I turned on the A/C and off again a few times, and it seems the noise does change. However, this could have been from coincidence.
When the jeep is warmed up and driven for a bit, the whine is barely noticeable if at all.
Here is a video of the sound. I know the wind noise blocks out some of it. http://s981.photobucket.com/user/dou...ee964.mp4.html
Secondly, I have this ticking/clicking noise coming from under the hood. It is coming from the black can looking thing that is pointed to in the picture. What is this noise?
