Noise right after turning car off...

[HIe34]

Right after I turn the car off, I get this noise that sounds sort of like an electrical antenna going down. It's not constant like that though, it more like 3x with about a second or two in between. It seems to be coming from within the instrument panel.

No A/C running, defroster, etc. Any ideas?

Is the noise not there when the engine is running?
Could just be the heater valves opening and shutting if your heating isn't full on or off.

Hard to tell if it is there when the car is on (my car is kinda loud), I don't think so though. I don't think it's the heater valves because my heater doesn't work

lol yeah, sounds like the usual, it's kinda loud isn't it...
"nee nrrrrrrrrr nee nrrrrrrrr nee nrrrrrr"
so annoying...

I get something similar as well except it's when I turn to position 1 or 2 (I forget) but before I turn the car on and it sounds similar, but kind of a fast grinding buzz.

I'm not too worried, more curious I guess.

You know, I have had the same thing with my car since i got it, but i always forget about it until i hear it again. [Somtimes my seats squeak alot when getting out so i dont hear it] Mine sound is kind of soft, like there is a motor of some sorts with a gear on it, trying to move but backs off and then tries again, it dosnt last more then 10 seconds with me, I thought it was just some otehr part of the car doing its thing :P

No ill effects with the sound that i know of yet, I am going under my dash again to replace my Fan blower resister this weekend maybe i can have a look and let ya know what i see/hear

The noise you're hearing is the wiper arm pressure adjusting device.


Item no.4.

It is a motor independent of the wiper motor that increases the wiper arm pressure against the screen to prevent the wiper arms from lifting off the screen at high road speeds. It's a whirring motorized noise that appears to emanate from behind the instrument cluster.
It usually begins within 30 secs of start up and also occurs again just after shutting the engine off.
The noise lasts about 5 to 10 secs and is quite loud.

the motors resest for a few seconds after you shut down.

You probably didn't notice it unitl you got the AC fixed and ran the system.

Once again, another mystery solved on this board. One less thing to worry about.
