Prius C :: Blower Chirping Noise On Lowest Two Settings
Jan 31, 2014
Only on the lowest two settings fan makes a chirping noise, it is a lot worse with the colder weather. It has been going on for over a year now and when I get the oil change I bring it up and they refuse that they hear anything... Finally made appointment for it and they still claim they hear nothing. It sounds exactly like the link here on YouTube... there is also videos on YouTube with tacoma's with the same problem but there is a Toyota Service Bulletin for it.

I have been noticing a rattle noise coming from the a/c vent with the setting on the lowest. What this may be?

Two 2002 Camrys.
This car is so quiet that the fan is really irritating at any setting above lowest.
Is it replaceable?

I have a 2006 Accent and recently the interior lights have gone dim and the switch to adjust them does not make them brighter nor dimmer, why this has happened? I don't usually have it on the brightest but not the lowest either and now it seems to stay on the lowest setting.

I'm getting this weird chirping noise from what sounds like the A/C and Heat fan. When I turn it down it is noticeable and sounds like something needs oiled. Kind of like pieces of plastic hitting each other over and over again. When I turn the air up there's no noise but probably because the air rushing out is so loud. I'm thinking I may need to take something out and oil it up. Too cold here to do my own thorough investigation.

My truck started making what I would describe as a wobbling noise on settings 2 and 3 of the blower fan last week. Yesterday I went to leave and started the truck the fan was on 2 and the selector was set to floor, I went to move it to the floor/defrost option and heard what I can only compare to the grind/screech you hear when you try to start a car that's already running, then a pop and it returned to it's normal quiet but slightly wobbly sound.
I am assuming my blower motor is warning me of it's plan to call it quits in the near future. Doesn't look like a big deal at all to change, but my question is - is there any quick/maintenance clean-up type tasks for these or are they just replace when they start issuing warning threats?

My blower fan will not run on setting 1. on 2 3 and 4 it will work but not on the lowest setting. I replaced the relay and it still doesn't work. I have a 2010 f150 with the 2v 4.6 .....

Thought for sure that would fix my fan speed, but nope. Replaced blower control module, Still only blows on the highest setting. Didn't try running it on auto, but that's what it did on manually turning the speed up. What else could it be?

There is a chirping sound coming from the engine of my 2010 Prius. It sounds like a really fast bird chirping and my guess is its probably the serpentine belt. It is there as soon as I start car and the engine is running. 80k miles.

I was wondering if this problem is the "Barking" noise that keeps coming up the search or is it another problem. I will include a link to the video down below.
To start off, the Prius is 2010 Prius II and has 120k miles on it. Great Car. Only other problem was AC compressor dying at 90k.
The chirping noise happens when the brake pedal is pressed and does not go away until the release the pedal. It makes the noise regardless of whether the car is on or off.
It makes the noise when the car is stopped and or when the mechanical brake engage at between 0 and 6 mph.
Noise does not occur when the brake switch is removed. Not valid solution since the brake lights will stay on. It does not affect the performance of braking.
Here is the link to the video .... .... ....

Mostly while negotiating in very crude camp ground roadways, we started to hear a new noise. This started before the incident I will be reporting in my third thread, so I do not attribute this noise to that incident. The noise seems to come from applying the brake when the car is already stopped or nearly stopped. Its a bit of a chirp, but it is a low-throated chirp. It think they come in twos, "chirp, chirp."

There is a pretty loud continuous clicking noise lasting about 30 seconds (not necessarily a bad one - just annoying) that comes on every thirty seconds to a minute when I'm driving my Prius. It happens more often now than it did 10,000 miles ago.
It also happens without fail for a few seconds every time I brake. Is this a normal noise? I fear it may be associated with the brake actuator--which the chirping noise is associated with.
If I press firmly on the brakes (which is rare), they chirp. Toyota released a bulletin on it. TSB BR001-07

I want to say that I love my prius but I am having an odd (although minor issue).
When I accelerate a I hear a noise (it sort of sounds like a cricket rapidly chirping, only a lower pitch or maybe a phone on vibrate).
What this could be?

Tonight I was driving home and the warning light came on. Thursday I was driving and noticed that the power lurched a few times. I switched over to see the energy usage and noticed that the battery was at the lowest bar. It stayed there for about 10 minutes. I called the dealer and started to head there. As I was talking the bars began to rise. It has seemed fine for the last few days until the lights came on tonight. I had just put gas in it. However, the car seems to run just fine and the traction battery seems to be charging just fine. There was no loss of power. Here in Texas it has been over 100 degrees for many days. I had an oil change at the dealer 10 days ago.

I recently hear some light noise from AC/heater fan at lowest setting (1) - its like the faint motor noise you might hear in spinning motors (sort of like ticking but not quite). I don't recall hearing it before. At higher speeds like 2+ you hear air blowing out which overpowers any faint noise you might hear. Noticed this while using for heat setting. Haven't tried for AC as its winter now.
So I was wondering if this faint noise is anything to be alert/concerned about in terms of operation of my AC/heat fan. Would hate for it to die on me one day when I need heat/AC.
Car model is Suzuki Forenza 2006, not that it matters I assume.

My prius that I got about 1 1/2 years ago (2013 model) was making some noise. After conducting a few experiments I came to the conclusion it was the heat that was causing it. I removed the glovebox and lower plastic panel as well to see if it was actually the blower that was making the noise. And it was the blower.
So now it's like 20 degrees outside and I haven't used the heat because I didn't want to blow something so gotta get this fixed ASAP.
Like I mentioned glovebox and lower panel are open I've removed 2 of the 3 screws necessary to remove the blower. So the problem lies with the 3rd screw. There is a plastic socket with wires that is preventing me from reaching the 3rd screw so I have to remove that socket. So I have a couple pictures and how I can remove this so I can access the blower motor.
Also isn't it strange that the car isn't even 3 years old and the blower is giving me problems?

My 2005 Prius has always made a light ticking noise whenever the blower air fan is on. It adjust noise and speed when adjusting air speed.
I have replaced the cabin filter with no luck. It almost sounds like a leaf or paper, but I can't see or reach anything in there to fix it.
Is there a DIY write up to remove the blower? I suppose I will see if there is anything to clear out, or potentially just replace the unit.

Purchased 2011 Prius 2 with 108500 miles on 4/29/2015. Didn't fully check all climate control settings and fan speeds. Two days later, car had vibration and rumbling sound which was increasingly severe on three highest climate control fan speeds in all modes (e.g. AC, heat, auto, manual, etc.). Sounded like a quiet lawnmower on highest fan speed. Was quiet on three lowest fan speeds. Glove box and passenger side dash vibrated in sync with noise.
Cabin air filter had been replaced by a large Toyota Dealer as part of pre-sale prep. I suspected filter was not installed properly. Removed glove box and filter, which had been properly installed. Vibration/noise were same when fan was operated without filter or glove box installed.
Felt around inside of fan housing. There was debris, including seven pieces of acorn shell (see image below). The concave sections of the shells were firmly wedged in the fins of the squirrel cage (no pun intended!) impeller. Cleaned out all nuts and debris, reassembled, fan operated quietly without vibration at all fan speeds.
The shells essentially unbalanced the impeller and induced vibration at high fan speeds, just like an unbalanced wheel would induce shimmy or vibration at freeway speeds. What is baffling is how the debris and acorn shells this large got past the filter. Filter fit on the right side is pretty good since a plastic flange goes between the pleats. The left side appears to have a looser fit with some gaps.

I noticed that I have an unusual "rumble" noise coming from the location of my ac blower motor when it kicks in full blast. When the air temp comes down a bit and the AC slows down or if I switch the ac off full blast under climate control, the noise goes away. I have never noticed this before and am wondering if it is my ac blower motor starting to fail.

There's been a recent annoyance that's appeared in my '03 SC 430 with 32K miles. I've noticed over the last 3 months that whenever I have the A/C turned on, after a few minutes, a soft chirping sound appears. It sounds very much like a cricket chirp to be exact, kind of high pitched, but continuous. It's even loud enough to hear over my music.
I realized that it came from the A/C because it was gone whenever I turned the A/C off. I initially thought it might be from the belts for the A/C compressor, but I couldn't hear anything from the under the hood with the A/C turned on. I'm thinking it might be something to do with how the coolant flows in the lines, but can't be sure.
I'll probably have it looked at during my next oil change.
