Whistling ??? Noise
Well I am new to this forum, I have a 1999 C5 and have had it for about 5 years now. About 2 weeks ago a rain storm caught me driving home, the next day after turning on my car a strange whistling noise came from somewhere in the front by the throttle body. Took it off, cleaned it and still I had the noise. A friend of mine told me that water could have gotten into one of my pullies causing the noise. Any help will be greatly appreciated.. The sound is even louder when revving the engine.
I cant upload the video of the car onto the forum, file is to big. If you can help me out i can send video to an email.
Once again thank you in advance!!

I would then begin checking for an air leak (ahead of the throttle body) or vacuum leak (downstream of the throttle body).

That is what I would do first.Here is something to supplement that:
Buy an automotive stethoscope which are very inexpensive. Have some one help you with the throttle and see if you can pin point the problem or narrow down the area.
If you have trouble in finding it I would be glad to look at your video but I doubt it would help me or us.
