Lexus SC430 :: Loud Sound Behind Center Air Vents?
Nov 24, 2005
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.

I have a high mileage 2002 SC430.
I have noticed that when I start the engine on a cold morning and start driving right away I hear a distinct "cracking" sound from behind the air vents (dash area) when accelerating. This only occurs when the engine is cold and when I am accelerating, this does not occur when the car is parked (I have not tried revving the engine when the car is parked, since it doesn't seem like a good idea).
A a side note, I do typically move the temperature setting to the max of 85 degrees on cold mornings, but the cracking sound often comes up 5-10 minutes after I change the temperature setting. I'm not sure if this has anything to do with it.

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?

How to remove the center console where the gear shift is? I need to get access to one of the audio connector under/near the gear shift. I am looking to add an audio auxiliary port.

Car sat there for 2 days non driven. Started it up, turned on the AC and it wouldn't blow through the front vents no matter what "mode" I select whether its on vents or legs. Instead it only blows through the windshield ones for the windshield. And it is also blowing outside air or maybe hot air, regardless what temperature I select and with the "AC" button on.
Before when I would press the "AC" button while the air was running I can hear a compressor or some clicking sound which is normal but now there's no sound when I press that and no sound when "mode" is changed.
What I've tried:
All fuses, all are good.
AC relay (good).
Disconnect the battery for 10 min, reconnect. Nothing.
Repair manual suggested action where it displays some codes. (I failed to link those codes to a proper definition in the manual)
Its been 90+ degree here in CA. I cant drive this car without AC.

I have been getting a sound like a loud cpu fan on the driver's side of the console wall, just below the ignition port. Any other NAR cars have this problem? It will go away after awhile but will turn back on again.

I have been getting a loud, high-pitched mechanical-sounding noise coming from the middle of the dash, near the CD player. It lasts only a few seconds, but it scares the sh!t out of me every time! It happens out of the blue after I've been driving for a few minutes about every 3 weeks or so. The sound is almost impossible to describe...but if you've had it happen you probably know exactly what I'm talking about. It happened today while I was listening to a CD, so I can't imagine it's the player that's doing it. Non-Nav/Air V8

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.

I replaced my brake pads and rotors and now the driver's side brake has a loud pitched squeal. It doesn't squeal all the time and if I let up on the brakes and apply them it goes away.
I think maybe one piston is hung up.
How do you free up a stuck piston in the caliper piston?
Or could there be another reason for the squeal.
I installed Callahan slotted rotors and ceramic pads on all 4-wheels.

I took apart the whole center console and then got to the harness which then I cut the speed sensor and then grounded the park brake bothe wires are violet/purple on the #59 harness which is the biggest harness on the back of the nav unit. It was working and everything was fine, I was ready to run wires for the double pole switch and then the DVD had no sound so then I tried several things and still didn't kick in so then I left it that way and waited till the morning and its like the DVD has a back up speed sensor that kicked in so when you come to a complete stop it works.
I know of another speed sensor 2 but that controls the nav so we dont mess with that wire.
Taking apart the car was easy 4 screws and 1.5million clips and snaps.

So I've noticed an annoyance with my car lately. I've noticed when I turn either right or left upon starting my car, that i hear a small sound, as if a marble is rolling along the inner windshield but it never runs the entire length of the car to the other side. I have noticed when I make a right turn, it occurs on the right corner of the windshield. When I make a left turn it occurs on the left corner of the windshield. Never runs all the way across the windshield like something is actually rolling along the windshield edge or behind the dash.

I have owned 2 SC and I notice both of the SC I have owned get a odd " hissing " sound, when the ignition is turned to the " On" position with the key located in the engine area, It will come on and then go off ...
Sometimes this " hissing " sound will come back on when driving and then off again ...
Hissing sound when the key is turned only to the "on" position?

I have had my '02 SC since 2007 and frequently when I turn the key to start, I hear an instantaneous "electronic click" sound. I have ignored it and no service person has ever mentioned it, nor have I requested a Lexus diagnosis.

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.

So, last night I was driving with radio off and a "whirring/fan" sound was audible in the rear of my 2002 SC430 - a sound that I have never heard. The sound seemed to resonate from the driver side, access panel (which I believe holds fuses and other systems for roof). After the vehicle was stopped and restarted the sound continued. Now today, I insert the key into the ignition - no sound; turn to accessory - sound is audible; started vehicle and did not hear sound. Second time I repeated and sound was heard; started and did not hear sound, Third time I repeated and no sound heard in accessory start position. What the heck is this? Any diagram of the trunk and what components are housed in the center bay? Does this vehicle have any auto-leveling function that activates?

I'm I just purchased a SC430 2002, car make a clicking noise when shifting gears. Example when I turn my car on and shift from Park to Reverse I hear a clicking noise and then when I go from Reverse to Drive it makes a clicking noise. Sometimes it just goes away. Is it a transmission issue or if this is a common sound.
