When I closed the hood I heard something hit the ground under the engine. Saw this (pic) laying on the ground. I have not started the truck since...don’t want to do damage - any help identifying this part and what to do next would be greatly appreciated. Thank you in advance to my fellow Hummer enthusiasts (I’m new member so my apologies I posted this in new member area as well...still figuring out protocols here)
Thanks bonxteck - it did look like some type of horn to me as well so I hope your correct - when my alarm goes off it honks my h2 horn though so I didn’t think I had a alarm horn/whistle.
What fell off my engine
