noise from under the hood when the ignition is on

Hello all,

I recently noticed that when the ignition is on but engine is off, there is some noise coming out from under the hood. I found where it came from but do not know what that really is.

In the following video, you can see and hear there is a metal stick behind the plastic grids moving while generating the noise. The picture gives you an overview of where the plastic grids locate. The noise goes away after maybe 20 - 30 seconds.

Video:

Does any body have any idea? I appreciate your insights!

Thanks!

That is interesting. I will have to check mine when I get home. The area in your video and picture is the master brake cylinder and the brake fluid reservoir. You can remove the "plastic grid" for a better look by pulling up the rubber strips and then compressing the clip in the lower right hand corner of the "plastic grid" and pulling it up.

Yeah I don't get that unless there is a small amount of play before the wipers move

Thank you for your reply! But I don't think the wipers were active. So wipers were turned off actually.

There have been times when I shut the engine off the wipers move about an inch or so then go back to their normal position.

Yeap. Have seen that happened too. Seems normal with the wiper movement but not the sound as in the video.

Don't know about the sound but do know that the wipers are programmed to move on vehicle shutdown every so often to keep them from sticking to the windshield. This is normal behavior.
