Prius (2004-09) :: Buzzing Noise From Under The Hood When AC First Turned On
On our 2008 (26,000 miles), I've started to notice a "buzzing" noise (best way to describe it) from under the hood when the air conditioner is first turned on. Never noticed it before, but that doesn't mean it wasn't there.
If I drive the car with the ac on, then park the car for 30 minutes or so, it seems to not occur when restarting the car and the ac. A little vague, I know. Sound normal to you?
Mercury - Grandmarquis :: Buzzing Noise Under The Hood
Several minutes after I start driving in the morning, my car starts making a strange noise under the hood. It sounds like a motor running, or a strange buzz. After a few minutes, the noise stops stops. When it does, and if I'm stopped at a light, my engine jerks one time. The engine actually shut off one day, but I could start it right up. It does this once during the trip. The speed of the car or engine has no effect on the sound, but it stops if I turn the car off. If I restart the car, the noise does not return.

I have a 2011 f250 6.7, I park under my house everyday, so I am used to weird noises coming from my truck when I shut it off, but now that I just did a dpf and egr delete, and tuner, I noticed that my tuner doesn't shut down until the noise under the hood stops, which takes a few minutes to stop, I use to hear the air valve on the egr cooler shut when every got quiet, but I don't remember it lasting this long, any one else have a H&S mini max and it doesn't shut down right away? the place where I bought my mini maxx said it should shut down as soon as your head lights go out, but that's not the case, the headlights go out long before this noise stops and the tuner powers off

I noticed for the last couple weeks, my wife's 05 Limited has developed some kind of buzzing sound around the dash on start up.
In the morning, once I get in and press engine start, there is a buzzing, d...zzz..d....d..zzz.zzz.... noise coming from the dash area. I turned the car off and restart, it went away. It happened once a while. This morning, same noise, I kept on driving, probably after 30 sec, it stopped..

View 4 RepliesAvalon 2005-12 :: Loud Buzzing Noise Coming From Rear Window Area?
I have a 2005 Avalon Limited. A couple of weeks ago I put the car in reverse and I started hearing this loud buzzing noise coming from the rear window area. I narrow it down to the rear window sunshade. It also makes this noise when pressing the button to lower the shade and maybe sometimes rising it. I know it has something to do with the relay or motor when the signal is sent to it to lower it, because a lower the shade signal is sent when the car is put into reverse or button is pushed. How to find the motor or relay without taking the rear seat out. Right now I would rather just disconnect it to stop the annoying buzzing noise. Where can I find a service/maintence manual to maybe find out how to disconnect it.

Just lately, I noticed a buzzing noise emanating from the glovebox when my car starts up. It goes away probably in 20 secs or so, and it's very pronounced when the outside temp is hot. When I was replacing my cabin filter, I found the source of the buzz. It's black box below the cabin air filter, to the right, with a 6-pin (?) molex. What this part is? See attached pic for identification.

I have been getting a buzzing sound under my hood, usually in cold weather that lasts a few seconds, happens after I go about 1-2 miles from my house, did online research and it might be my IAC valve getting internally dirty.
Could replace it for $50.00, some You Tube videos show people cleaning theirs on other brands of cars, can the Ford IAC valve be cleaned up with a little carb cleaner and cotton swabs?
Nissan - 200sx :: Buzzing Coming From Under The Hood When Make A Relatively Hard Right Turn
I'll be driving along, and when I make a relatively hard right turn, I'll hear a buzzing coming from under the hood from that point until my destination. If the car is stopped (usually about 10-20 mins) I'll start it back up and no buzzing.
I've tried pulling over and stopping/starting the car with no luck. I've shifted gears, including into park and neutral, with no luck. I"ve even tried a hard left turn (no luck)!
The buzz is not terribly loud, but rises and falls perfectly with engine RPMs. At idle it's not noticeable, but increases in pitch with the RPMs. It sounds like the engine sounds on a really cold day before it warms up. If I put it in park I can rev the engine and reproduce the same effect as when driving. It doesn't go away at a certain point i.e. I don't think it's resonance.
This is a 1998 Nissan 200SX with about 90K miles.
Chevrolet - Silverado1500 :: 2000 - Buzzing / Whining Sound Coming From Under The Hood
I recently replaced the fuel pump and afterward started noticing a buzzing/whining sound coming from under the hood. The noise goes away when I remove the vacuum line from the fuel pressure regulator and after the car has been driven for 1/2 to 1 hour. Sometimes it comes back, sometime not, but it always is there at a cold start. Had the shop take a look and they said the fuel pump is ok and recommended replacing the fuel pressure regulator. I did but that but it did not solve it. I suppose I should check the fuel pressure. 2000 Silverado 5.3L ...
View 1 RepliesPrius (Gen 2) :: 2005 Stalled - Clicking Sound And White Smoke Coming From Under Hood
I have a 2005 gen 2 Prius, 106k miles. Recently in Florida, we had a heavy rainstorm, and I happened to drive it through a flash flooded road. Water was deep enough to reach my headlights. I was out within 10 seconds, then had my car towed. There was a clicking sound and white smoke (steam?) coming from under the hood. The car would start, and I could drive it if I wanted to. After talking to a mechanic, he said to let it sit for 30 minutes with the engine on. Like magic, it started to work like normal, check engine light went away.
Drove fine for 2 days, then the check engine light came back on. Had the codes read at autozone: P0103, and P0031. One day later, my car stalled out while I was driving, and the dashboard lit up like a Christmas tree. Red triangle, yellow exclamation, brake, abs, "problem" on mfd, etc. This site has saved me before, so I came on and thought it could be the MAF sensor. I cleaned it with MAF cleaner, but no luck. I order a new sensor, still no luck. My car stalls out seconds after starting it up. I cleaned my throttle body, still nothing.
Mercury - Grandmarquis :: A/C Malfunction - Buzzing Sound From Under The Hood - Brake Warning Light Keep Coming On
I'm having several problems, and I'm wondering if they are related: Sometimes the heat/ac/vent blows on the windshield instead of where they are supposed to be. Occaisionally it works at first, and then changes after a few minutes to blow onto the windshield.
Sometimes I get a buzzing sound under the hood. Usually when I'm stopped, but sometimes while moving. The car idles high when this happens. If I tap the accelerator, this usually stops the noise and the idle drops to normal.
This morning, the brake warning light kept coming on while using the brake. The fluid level and pedal are OK, and the car stops OK. Then the buzzing sound came on, the engine light came on, and the brake warning light went out at the same time. The brake light hasn't come on since. The scanner tool indicates the IAC was running too fast.

Prius (Gen 3) :: Buzzing / Humming Noise From AC Fans - Is It Normal?
Was the warmest/hottest day of the year here so far and my black Prius had been parked in the sun all day. When I came to drive the car the a/c came on full power to lower the cabin temperature.
However, from the front of the car the two fans were making a really weird buzzing, humming noise (but were both spinning at high speed). Now I know a/c fans work flat out sometimes but I have never heard a noise like this before on a cars a/c. It almost sounded like the noise a jammed lawnmower makes, or some of the old lifts/elevators doors make. Almost an electrical buzzing noise of a solanoid but it was coming from the two fans.
Is this normal? Was it the fans or maybe the compressor or both? The a/c was working fine and was ice cold. When the cabin temperature reduced the noise reduced a disappeared with it. However, I did manage to repeat it by turning the a/c internal fan speed to full on a low temp setting.
Prius (2010-12) :: Whirring Or Buzzing Noise After Shutdown
I have a 2010 IV and after driving for an extended period and then shutting the car off I get a loud noise about a minute or a little more after shutdown. The best I can describe it is that it sounds like someone is dropping a 3 pound dead chicken from about 10 feet up onto my hood. It is consistent and is not any of the whirring or buzzing noises I normally hear. I also have a 2009 Touring and have never heard anything like this.
