Hey guys,
I have a 2003 Trailblazer <nobr style="color: rgb(74, 149, 225); font-weight: normal; font-size: 100%; font-family: verdana,geneva,lucida,'lucida grande',arial,helvetica,sans-serif;" id="itxt_nobr_1_0"></nobr> LT and sometimes when I drive on the highway there is this bird chirping sound coming from the front end. Its not there all the time but usually when the wind is blowing. Most likely its something vibrating under the hood but I can't figure it out. Sometimes it will be there for a bit then go away but on windier days it last longer(it gets louder when the wind blows). What could this be?
Any help would be great
Thanks

couple things come to mind---

with the hood closed--- grab the lip and see if you can move it up and down.
if you can-- open the hood- and on both sides- there are rubber stoppers--- turn them to raise them--- these keep the hood from bouncing up and down in certain scenarios.
Dont raise them too much- or youll have a hard time closing the hood--- leave them so that the hood is nice and tight-

If not- then open the hood-- and make sure the hood prop stick hasnt come out of its clip... and is moving around...

try those 2 things

I had that problem with our 03 when it was new. Dealer fixed it by lubricating with white grease the hood latch. I was told it as a known problem.
