Hello, I have a 2001 Ram 1500 st reg cab. magnum 3.9L smpi V6 with about 90k miles.
Just this week a very loud vibration and noise started happening every 12-15 seconds and lasting about 5-10 seconds for as long as I have the engine running. There has been no noticable change in performance along with the noise. If I had to describe the noise I would say that it sounds very much like an old door creaking open or plastic vibrating against plastic.
I was able to find the source of the noise/vibration by feel and sight, it is definitely coming from a casing under the passenger side of the dash, accessed from inside the cabin, however, looking through my owner's manual and my Haynes manual I have been unable to find any reference to what this part may be. I would like to know the name of this piece so that I can research the problem online and see if it's something simple that a layman can DIY.
Any help would be appreciated, I have taken photos of the part in question.
the part. unplugging that wire stops the problem.
