Lexus SC430 :: Loud Buzzing Sound From Dash?
Aug 21, 2012
I have recently started to hear (at frequent intervals) a loud buzzing sound that can best be described as a phone vibrating/buzzing while its on a table. The sound happens every few minutes and is pretty annoying. It seems to be coming from around the navigation area or glove compartment - i cant pinpoint it. I turned off the radio and AC and the sound is still present. My Navigation Wood cover has been STUCK for a few months (doesn't come out and shut nor tilt) but not sure if that is the cause here. What can be causing this sound?

Have had SC430 for over 10 years, 94000 miles. Have loud buzzer sound behind dash on startup or when key is turned to on position. The sound last 10-20 seconds and goes off. I have turned the AC off and tried different modes, no change. Everything seems to be working fine with the AC. Could this be a servo motor, the noise is not coming from the engine compartment. Any thoughts on problem and how to fix it. It makes this sound on every startup.

It just happened yesterday on the freeway, as I hit a small bump. Need to mention this stretch of freeway has those extremely annoying ridges that make everything rattle inside the car, besides the deafening tire howling. But after they're gone, all used to be well. Yesterday, after said bump, this very loud noise behind the center air vents started all of a sudden. It increased with speed.
Sounded like a motor turning. Thought it was the NAV motor (which I never use), but opened it and closed it, and it functioned well. Tried the motor for the stereo cover, and also worked fine. When the motors were operating the sound persisted. The noise disappeared below 50 mph. And not even in broken pavement was present. After speeding above 50 again, now in smooth pavement, it was back. I guess it's there to stay... until 'killed'.
I HATE dealers going on a fishing expedition in my cars, so prefer to know what the heck is causing it, and preferably do it myself (don't trust the only dealer in town). I'll try to tackle it myself, but no way I can live with that noise, so a trip to the dealer seems almost certain, as I don't have a service manual yet to get behind the dash.

My left headlight has been going off periodically, so to confirm that it's the bulb, tonight I switched the bulbs from left to right/right to left.
The job went very smoothly. It took me about 20 minutes, but I took my time. I buttoned everything back up and turned on the lights. Both sides came on, but I immediately noticed a very loud buzzing/whining sound coming from both headlamps. It is very loud and I know I would have noticed it before at some point over the course of the last three years that I've owned the car. Obviously, this is not normal, but I can't for the life of me figure out what I could have done wrong, if anything.

Squeaks, rattles and anything else that makes noise (other than the stereo and especially my wife) You can imagine my total horror when I went around a corner and I heard what sounded like a marble rolling through the roof or dash of the car. I've been able to replicate it a few times but I have to be cornering pretty hard to get it to do it. I have had 1/2 of the top apart.....3/4 of the dash apart, under the hood, in the glovebox and console as well as underneath the frame and I cannot for the life of me find the source of the noise.

Just got stage 2 tune with tbe and bhs pendulum mount. Loving it so far but there is a loud buzzing coming from the dash area every time I hit the gas. There is more vibration in the car now that will probably stir up some rattles but this one is pretty loud!! Doesn't sound like it is in the engine compartment but more like on or in the dash by the radio or climate controls.

Recently purchased a 2002 sc430 with 80,000 miles on it. Car drives like a dream but I have a noise coming from the backseat. Rear Passenger side ,upper back area. Best way to explain it is that it sounds like a small fan???? Comes on here and there as I drive .

Tried to start my truck after sitting for 2 days in sub zero weather. wouldn't crank. pulled the batteries and charged them over night. Tried to start it the next day-wouldn't crank but the starter relay clicked. Was going to pull the starter and check it but decided to replace the relay first. replaced it and tried to start but now have no power to the cab-nothing comes on. I've checked the batteries with a load tester and they are ok. I've checked the fuses and they seem to be ok. when I tried to start it and the relay clicked there was a loud buzzing noise that seemed to be coming from under the dash. it has done this before but this time was louder than usual. I live out in the sticks so taking it somewhere is a last resort. It is a 1999 7.3 with 290000 miles.

I have a 2nd generation prius and up now no problems but today my car continously makes a pretty loud buzzing sound if the car is on or off. No lights are on other than the maintenance reminder light as I currently have 57000 and waiting a little longer before I bring it in for the 60,000 check up.

Recently purchased a 2002 sc430 . After an hour of driving I began to hear a buzzing or humming coming from the backseat on the passenger side . Sounds almost like a fan. Car drives just fine but the buzzing is driving me nuts.

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..

There is a constant buzzing/clicking sound that seems to be coming from my navigation in the dash. It makes the noise all the time, not just at random times. It sounds as if the nav is trying to load something constantly? It is really strange, also sounds like a computer when you first start it up with the clicking and buzzing.

My 2006 Prius with 206k miles is making a loud buzzing/grumbling noise when I press down the brake and periodically when parked. It's coming from the general area of the brake pedal, under the steering wheel. See video for a recording of the sound:

A few months ago, my car started making a loud whining/buzzing sound when I started it. The sound is distinctly coming through the speakers in the car, but turning the radio volume knob doesn't make it quieter or louder (though turning the radio completely off makes the sound stop). The sound persists until the car warms up, then the buzzing sound slowly fades away, and the voice/song on the radio slowly comes back until the buzzing sound is completely gone.
I recently took my car to a mechanic to have the timing belt and head gasket replaced, and the mechanic couldn't figure out what the problem was. What could be the root of this problem? 2006 Subaru Impreza 2.5 ...

Today while driving form CT to Maine my 2004 Legacy started making a buzzing sound. It was on the right of the dash near the corner of the windshield. It only happened once we went around 75-80 mph (Mass Pike, we were going with the traffic flow). I called the dealer since I got the car only a month ago. They said they'd have a hard time figuring it out since they can't take it up to that speed. My husband thinks it might be the speedometer cable.

ok this has me stumped I get this buzzing/humming/vibration sound from what seems like around Defroster passenger side but it is not all the time only at higher speeds and it it intermittent . I have removed cabin filter and cleaned filter box and checked for a leaf or something even sealed somewhat the plastic shield that covers the cabin filter. I really don't want to rip dash apart but it is so annoying

I have had a 2000 f250 crew cab for little over a year now. Two previous times, after heavy rains, the cabin light would blink on and i would get a buzzing sound under the dash. I would solve the annoying buzzing sound by opening and closing the door. After a few times, it would work, but my clock and radio could go on without the key in the on position. The next time i used it, no problems... so i put that worry in the back of my mind.
This morning it rained really heavy, sideways type of rain. I opened the door and noticed a small puddle on the vinyl floors right where my left foot goes. OH,oh i thought, but the truck turned over and ran like normal. I picked up a heavy load of hickory in the bed and hopped back in and noticed my speedometer jumping from 0- 30 when I was going about 35. The OD light was blinking, but the transmission shifted normally. I got up to about 1700 rpm and the speedo was barely jumping at 53-55. I make another stop to unload the wood and go back home and i get an intermittent buzzing sound on the way home and no speedo. OD light would start blinking before i hit 2nd gear. I also noticed the odometer not working (speedo related, right?)
I got home and took the fuse relay cover off and found that if I would remove the #1 relay "plug" (black square box 5 prongs) that dreaded buzzing sound would go away, checked it out , plugged it back in, buzzing back on. The clock light still stays on and radio will turn on without the key. I think that water obviously leaked in over something electrical and i have been searching this and other forms for a couple of hours. I am within a couple of weeks of saving up enough to buy the gauges, exhaust and possible DP Tuner and now this happens?

I've been having an electrical issue for the past few months that I've decided to address now that the weather is getting a little warmer.
What happened is the left turn signal was blinking fast, so I assumed bad bulb, and later that day it stopped blinking fast and now I press the lever down to indicate a left turn and there is a quite loud buzzing sound. Sounds like it's coming from where the relays are, but I've replaced them and the bulbs and still nothing has changed.
I've also replaced the multifunction switch to see if that was an issue, but a new one did the same thing so I returned it.
Running lights work all around, but now there are no left blinkers, and also my left brake light doesn't come on. Pulling a trailer I have the same problem, I had the plug tested and only 3 of the pins have anything to them.
I know nothing about auto electrical systems.

i keep hearing a noise under the dash by the radio. it is almost a gurgling noise if that makes sense. i don't know if it is the cd player doing something, or something else.

We have a 2004 and 2007 SC.
I notice that the dash lights on the 04 are dim compared to the 07 even though the dash control switch is turned all the way up. Is this the nature of the car or is there a setting that can be adjusted through the computer?
