I have the 3.0L Duramax diesel, and on random cold starts there is a buzzing coming from behind the dash. Haven’t been able to find where, sounds like two plastic pieces vibrating against each other. Anyone have happen to them? Tough since it doesn’t do it consistently. Attached a video of the sound. 4b67c43a-b3fd-46f3-b834-e703b37aad0a_compressed.mp4
Greetings and happy holidays! Thanks in advance for reading and sharing your experience. SITUATION MAKE: CHEVROLET MODEL: SILVERADO 2500HD REGULAR CAB YEAR: 2001 TYPE: PICKUP ENGINE: GM VORTEC 8100 V8 8.1L (496 CID) ACCESSORY PACKAGE: LS ISSUE: The truck is in good shape for the age and has about 74,000 miles on it. Drove it all day yesterday making a thousand stops for last-minute Christmas stuff (good job there) and everything was fine - no weird sounds, trouble starting or other issues. Jumped in it this morning to go after some eggnog (disappeared last night somehow) and it would not start. I had bright lights, loud horn, and the door-open dinger was blaring as usual, but I got no crank at all. Instead all I could hear was this weird electrical buzzing sound.

Has anyone ever had, seen, or heard of this before?
