Weird AC/Turbo Spooling Noise

[ne0guri]

Not sure any of you are experiencing this issue, but there are times when I'm driving (with AC on) and I hear this crazy wiiiiiiiinggggg weeeeeee sound. At first I was thinking it was the Turbo, but after playing around with the settings, I realized after turning off the AC the sound would stop as well.

Anyone else hear this noise or can explain why it's doing that?

Yep, me too. Just started at about 7,500 miles. It doesn't sound good.

Mine had made this sounds since day one.

It's probably just the AC compressor

My 1995 Sc300 that I traded in did that and I'm not sure if it was an electrical issue as well as the noisy compressor or just the latter.

My SC400 did also during its entire lifespan

As does my wife's 2012 Accord LX-P

And the Sc400 had electrical issues maybe relating to or not relating to the HVAC system and did you memory seats not work in the end?

Everything worked - 92 with 105k on it.

Well, except the suspension which was busted. Didn't want to spend the $$$ on the lower control arms.

My fans make a similar sound when they are on a low fan speed with ac on. And only around lower rpms. It's really annoying when you notice it but it's very faint and gets louder when I rev up the engine almost like you can hear the fans spinning faster. I have a hard time getting my fiancé to notice. It's like I'm taking crazy pills or something haha. I should probably go to the dealer and get it checked.

It's confirmed, I got the raw end of the deal on the Sc300. Knew I should have went with the big V8 Sc400 from the get. I ha8 kar karma.

To be fair the Si is faster than both the non VVTI SC400 and the SC300, and would give the VVTI SC400 a good run
