Wierd buzzing sound in dash...

[SilviaSR20DET]

Hey, i have a problem with something buzzing in my dash and cant figure out what it could be. This only happens when i drive my car above 2500 rpm then the buzzing starts and i think it might be my exhaust rattleing it (i have a apexi n1 dual). Do you know what the cause of this problem or what it could be thats making that noise? Any help will be much appreciated, thanks.

Ok i just did a search and found a big post on the problem. It was exactly the same problems i have and seem to be common only on the 95-96 and 89-93 240 body style. Some say it was a worn ground wire of some sort and a guy said it was the egi harness. I really need to fix this annoying buzzing sound plz help. thanks

Could be the heat shield, I had the same noise when i first got my s13.

Something like that happens to me, and I think its either my keys rattling inside the ignition, or the plastic surrounding the gauge cluster.

Thanks for replying, so it could be the heatshield coming loose? Do i just retighten the bolts that hold the heat shield to the header? Cause i also hear some rattleing in my engine bay everytime a rev my car so it might be the cause of the buzzing noise in my dash also. Thanks for the help

[hookedup240]

yea, i just took mine off.

[RedlineRacer]

Yep, mine was the same way. But I could tell my noise was outside and not in the dash. I took those heat shields off like 2 weeks after I bought my car.

[SilviaSR20DET]

Well i took off my heatshield and the sound in the dash is still there and cant find what it is thats rattling still. Any other clues of what might be buzzing?

[RedlineRacer]

Tried looking in your glove box? Or behind your radio?

I think i just found the solution but not a 100 percent sure but pretty close. Theres a box near the accelerator pedal that im sure is making this sound because when i get under the dash and put my ear next to the box and rev my car i can hear it more than when im driving. My mechanic says the box is a heater controller. This is what made me so sure it was the sound because when i turn on the ac the sound is louder and makes weird noises. Im gonna go remove it and try to see if that thing is really the cause of this annoying sound. thanks for the help by the way.

I had this problem in my S13 it turned out it was the brake lines that run across the firewall in the engine bay. they were loose causing them to rattle. also it could be the line that goes to the ac it comes out of the firewall im not sure what side though that can also have a worn out grommet causing it to vibrate

by buzzing.. do u mean a little bee sound? cause mine is more of a chirp.. or i dunno how to define it.. but soundsm more or less like a chirp then a buzz.. but its coming from the dash area as well.. :duh:

[MELLO*SOS]

I have some annoying ass noise that comes and goes. A rattle of sorts that develops around 3000 or 4000 rpm... Sounds to be coming from the middle to right side of the dash, probably inside the dash or behind the firewall.

Reading this post someone mentioned a loose brake line, and that got me to thinking.. I broke a few of those brittle white plastic clips broke holding the clutch hard line in place, and I think that could be exactly what the noise is (line rattling against firewall). Thanks for the ideas!

its bound to happen when everyone hops on this thread with all their dash noises :Ownedd:

hopefully our problems come from a common culprit :x:

[omgosh]

My guage cluster makes a kinda electric buzzer noise...goes away at above 2500rpms or about 1/3 and up throttle...

anyone had this one?

[OdessaS13]

its a 10-15 year old car, im sure there is more than one reason there is one rattle or another, but yeah my shit buzzes too 1-2.5k somewer in dash ohh well
