Prius (2004-09) :: AC Starts To Make Whirring Noise And Just Won't Blow At All

So every once in a while, my A/C starts to sound like it's struggling. The force of the air gets stronger and weaker, and it starts to make a whirring noise (much louder than it should be). The temperature is fine, it's just the blowing air.

It will continue like this for weeks or months, then eventually when I start the car (particularly if I'm in my parking garage at work for some reason?!?! - could be a coincidence) the A/C won't blow at all. If I hold my hand near the vent, I can feel cold air - but it's just sitting there, not getting blown into the cabin.

Mitsubishi - Lancer :: Whirring / Growling Noise Starts Up A Second Or Two After Begin To Accelerate

Mitsubishi Lancer, 2003, 140k miles, auto transmission. About a week ago, I noticed a new noise coming from the engine compartment. It's not very loud, only a little louder than regular road/engine noise. It starts up a second or two after I begin to accelerate, and it winds down a second or two behind the rate at which I slow to a stop. It is constant when I am traveling at speed. The sound is something between a whirring and a growling noise, almost exactly the sound you hear when knobby bicycle tires roll quickly over smooth pavement.

The transmission fluid was about a quart low, and that got filled up, but the noise hasn't changed or stopped since then. I haven't had any problems with shifting out of/into gear. The car does occasionally "slip" out of gear in that when I am traveling slowly (stuck in traffic, usually) and going back and forth between light acceleration, coasting, and braking, once in a while I'll press the gas and the engine will just rev, but it won't engage. If I just let off the pedal, it will "reset" and then it moves just fine. It's done that ever since I bought the car in 2009, and it doesn't do it all that often, and only at those low traffic jam type speeds. So, I don't know if it's related to the noise, which is what I'm more concerned about.

Lexus GX 2004-09 :: Whirring Noise From The Engine / Smell From The Car

My wife has an 07 GX470. Two days ago she came home and mentioned there was a whirring noise from the engine. I started the car, lifted the hood and heard the noise. Sounded like it was being generated by the serpentine belt. Meaning, something that the belt was "driving" was making the noise. She drove it again yesterday morning for a 10 mile trip to drop off son at camp. When she came back, she indicated that it smelled. Just walking out the door to the garage I was hit in the face by a very strong electrical smell. No fire, but smelled very bad. Car has been sitting since yesterday morning and she just now tried to start it and the car is dead. no power to anything. Battery is new 3 months ago.

Azera TG (2006-11) :: 3.8 V6 Engine Whirring Noise At Around 2000 Rpm?

Question to everyone who drives an Azera out there. This is regarding the 3.8 V6 engine.Does your engine make a whirring noise at around 2000 rpm? Sounds almost like a supercharger whine, starts at around 1800 rpm and continues up to the low 2000 rpm's. It's not a loud noise, only audible with low volume music or none at all.

Phaeton :: Whirring Noise Coming From Engine Top Rear

Upon arriving home a couple days back, a rather high pitched whirring noise commenced while idling. The pitched changed seemingly at random. So I popped open the hood and set about locating it, using the time honored scientific method of leaning over the engine, listening and moving around till the noise was most prominent. The noise has not recurred.

Seems to be coming from under the cover at the back. Area of interest circled in the 2nd & 3rd pics.

What is there, and if it might make a whirring noise. I am also getting a p0491 and 492 Secondary Air Injection Insufficient Flow, banks 1 & 2. Wondering if this could be the culprit for that as well.

2002 Blazer - Low Pulsing Whirring Engine Noise At Start Up

I have an 02 Blazer w/ 110K miles. It's the 4.3L with 4WD. When I start it in the morning it usually has a low pulsing whirring sound for up to 30 seconds. It then goes away until the car is parked for a long time again, say overnight. It's a low volume sound, a lot like the sound of off road tires running down the highway. This has been going on for several months now.

All systems work fine. The alternator is new, the water pump has about 29K on it, and the top idler pulley has been replaced. Turning the A/C on or off makes no difference. The sound is loudest when you stand in front of the passenger side headlight which made me suspect and swap the alternator.

Could it be the belt? It was replaced with the WP and the ribs are not smooth inside. They are notched. I assume that's to improve the flexibility of the belt. If I take it to a shop they'll get 30 seconds each morning to diagnose it.

Elantra XD (2001-06) :: Whirring / Whining Noise From Engine At Idle

I recently replaced the water pump, timing belt and all other belts in my 2005 Elantra. The car runs great, but there is a whirring/whining noise at idle when I have the car in park and in drive when I'm stopped at a light. You do not hear the noise when I accelerate and you do not hear the noise at any speed above idle.

At idle the whirring/whining noise can be heard whether the A/C is on or off. I have done some research and some causes for a noise like that have been a bad power steering pump, alternator, or pulleys.

The Elantra has 106,300 miles and gives me 26 MPG. I love this car. It has been the most dependable car I have ever owned. I plan to maintain it and hopefully last me for another 100,000 miles.

Car (GMC Envoy) Grinding / Whirring / Scraping Noise Coming From Front Of Engine

Here is a link to the audio [URL] .... It makes this noise, whether I'm at idle or running, granted it seems to be happen more when moving, its quite intermittent as it stops sometimes. I replaced the serpentine belt a month ago, so it can't be that. Its coming from the front of the engine. Sounds almost like the fan bearings or something below that is scraping. I've turned off the heater and it still does it, but the fan is spinning all the time, so I'm not sure what is going on.In the background you can hear cars going by on the overpass above, but I'm focused on the grinding noise. Car is not moving, its in park and makes the noise when moving also, with gas or at idle.

Ford :: Focus 2013 - Scratching And Whirring Noise Coming From Engine

I just purchased a 2013 Ford Focus hatchback SE Monday night. Tuesday morning I came out of the house to get in my car, I unlocked the car, and opened the door. Before I even got into the car I heard a "scratch scratch scratch whirr whirr" coming from the engine. The dealer did not show me where the hood latch was so by the time I figured out how to open the hood the noise had stopped (within a minute of when it started.) Driving that day I did not notice any more noise, nor any issues with the engine.

Wednesday morning (today) I came out to get in my car, and when I opened the door I heard the same nose coming from under the hood. I got the hood open and looked in with a flashlight while the nose was still going. The noise was coming from the right hand side of the engine block, but I did not see anything actually moving to cause the scratching and whirring noise.

Lexus ES 2013+ :: Whining / Whirring Noise Coming From Engine While Accelerating Up To 45 Mph

I've got 2013 es 350 with 10,000 miles on now. I have recently noticed that there was whining/whirring noise coming from the engine(I guess) while accelerating up to 45 mph. It seems that the noise goes along with the RPM since it gets louder when accelerating. It makes same noise when decelerating from 30 mph and it goes away when the car stops. A friend of mine drove the car once before but did not hear anything until I told him about the noise, so I guess it is not very noticeable to some people. At the 10,000 miles check up at the dealer, I mentioned about it and they said they did not hear anything, but I know for sure there is whirring/whining noise.

Honda - Accord :: 1999 - Whirring Noise When Driving / Starting The Engine

My 1999 Honda Accord is making a whirring noise sometimes. It happens occasionally, now more frequently than last month. It sometimes happens when I start the engine, but am still in Park. Mostly it happens when I'm actually driving. both slowly on back roads and fast on the highway. What would cause this?

Lexus :: Loud Whirring / Humming / Whining Noise Coming From Engine

I have a 2006 lexus es 330 that just turned over 90,000 miles. My dad and I have done the regular maintenance on it so far but this weekend after a 3 hour drive, I turned the car back on and a loud whirring/humming/whining noise was coming from the engine. It gets slightly louder with acceleration, but I can barely hear it once I've picked up speed (but it's still there.) It still happens when I am in neutral. It sounds like it is coming from the passenger side of the engine. Close to the power steering pump area, but the power steering fluid is full (although it is a very dark/black color and has a slight smell...not sure if this is normal.) I'm not having any trouble or hesitation while steering. The rack is operating smoothly and it is not leaking. I plan on taking it into the shop but wanted to go in educated.

Toyota - Sienna :: 1999 - Whirring Noise Coming From Center Engine Compartment?

I own a 1999 Toyota sienna that has 112,000 miles. For the past few months there has been a whirring noise that seems to be coming from the center engine compartment. It started quietly and now has increased in volume. It reminds me of a speedometer cable that is beginning to fail. I have taken it to my trusted mechanic for a diagnosis and he thought it was metal on metal noise from the transmission. I have owned cars for 40 plus years and have'nt heard of this type of tranny noise. What could be causing this? It makes this noise under power and when I release the accelerator the noise almost disappears. Also there is a clunking noise coming from the passenger front wheel after releasing the brake pedal when I come to a stop. I have replaced the strut,ball joint,and lower control arm bushing trying to remedy this. I cannot find anything else that is loose.

Prius (2004-09) :: Electric Whirring Sound When AC Compressor Starts Running

I have a 2009 Prius with about 56K miles on it that I absolutely love. Now I know from reading in the forums an my own experience that when the A/C compressor starts running you hear an electric whirring sound. My question is... is it a cause for concern when the sound it makes seems different -- the pitch sounds lower to me now. The A/C still works fine, but I didn't know if this changing sound means the compressor was on the way out.

AMC - Eagle :: Random Hard Starts / Whirring Sound With Absence Of Crank

I recently got my(AMC Eagle '87) car running great again but now it doesn't want to start all the time! Sometimes it starts right up other times it take 5 tries or so. I turn the ignition and it sounds like it wants to engage and begin to crank but doesn't. It makes a sound like VRRR (like its about to crank) then just dies out and WHHHIIRRRRSSssss (getting quieter)... like something is just spinning. I did a couple tests on the wall mounted solenoid before getting rained out and it seemed to be getting juice flowing throw it. No difference in Ohms from testing the S Terminal and then the ground terminal. I also replaced my starter around 6 years ago. Does this seem like a starter issue? Bad solenoid? Bad cable? I really hope it isn't a flywheel issue!

4Runner/GX470 :: 1990 Toyota V6 Makes Whirring Noise When Key Is Turned But Engine Does Not Crank At All

I have an 1990 Toyota 4Runner. V6 engine. Automatic. 4wd. Today it blew an upper radiator hose. A few seconds after the initial pop of the hose and the spew of fluids the vehicle died. I replaced the upper radiator hose and the lower hose- and refilled the antifreeze. There are no leaks as of right now.

The engine will not start. The belts spin whenever the key is turned on. But the engine will not crank. You can hear the starter trying to start it up. Jumping the vehicle was of no luck. Charging the battery was of no dice.

The vehicle makes a whirring noise (belts spinning) when key is turned, but the engine does not crank at all. The noise stops as soon as you shut the key off. The oil is clean and full still.

Toyota - RAV4 :: Medium Pitched Whirring Noise From Passenger Side Of Engine Compartment

So my girlfriends Toyota RAV4 (2005) is making a medium pitched whirring noise from the passenger side of the engine compartment. (Same area where the serpentine belt and the alternator and all those goods are located.) The battery warning light is on, solid. I have not had a chance to take my DMM and check voltage but I suspect this is going to be a bad alternator since it is a noise consistent with the RPM of the vehicle and visual inspection of the belt is that it is still in one piece, not frayed, flexible, etc. I didn't rev the engine because I didn't want to freak her (the gf) out. My plan is to test voltage before she does anything rash like take it to the dealership which she is already planning on doing but the noise concerns me since noises tend to come from things that move which is probably an indication of some sort of mechanical failure and that tends to cost money. Luckily it's her car.

Civic - Honda :: 2000 - Engine Noise On Cold Starts

I have a 2000 honda civic with 120,000 miles on it. recently, on cold starts (when i haven't turned the engine for a day) i've noticed a rapid vibrating or rattling noise about 30 seconds or so after i've turned the ignition. this noise lasts for maybe 15 to 20 seconds then it goes away, presumably as the engine has warmed a little.

I do drive a lot, and during the day even after the car has not been running for a few hours this noise doesn't occur. Only happens on the cold starts. I hope it's nothing major. I've attached a video with the sound. about 30 seconds into the video you will hear the noise kick in. (if the video doesn't show below here is the youtube link: [URL] ....
