Weird Wistling

[crock]

Ok, this may sound weird. When I am accelerating with my music turned down and heat off, there is a whistling/ humming on the inside of the car. I am not sure what it is. I can tell you that my heat feels like it is on, but it is not. I just want to stop the annoying humming and the possibility that the heat is on. I can feel the warm on my legs. So my question is what may be causing this hum/ whistle? I do have my car ran for subs, so the little rubber fitting in the firewall is out. Could the heat be coming from there? Thanks guys. Help me! Its not major.... just annoying...

Maybe it's your sc.

[crock]

Im not retarded. Lol. I know the difference. When I put it in boost, you can tell the difference. The interior is whistling, not the supercharger...

[Tuner-Extraordinaire]

maybe you have a secret turbo.

[crock]

Arg! Yes I am a pirate. I just want help! Not saying that I have a turbo... Cause I dont. I own the slowest GTP in the world.

[Tuner-Extraordinaire]

Not evenz a lil one?

[crock]

Wow. No. I just want help. There is no turbo. I would know... Trust me.

Mine did that too... less noticeable after open cone intake..

Put your ear up next to the blower under the glovebox. My aftermarket one whistles when only turned up a single notch. Maybe yours is getting an itty ibtty dash of power and it's spinning.

Or you have a vacuum leak.

[crock]

Im pretty sure I dont have a vacuum leak. I might have a bad blower motor... But it even does it when it is off....

Where did you run your power line for the subs?

[crock]

through the rubber fitting... but I took it out today and put the fitting back in.

could be the turbro muffler whistle.

I have/had this problem too. I never figured out what it was but it went away and randomly comes back for a couple minutes. Sounds like almost the old radios did in cars from electrical interference in mine. but radio is off and its not coming from the speakers. and its quiet kinda? ide like to know if anybody finds out what it is too if ours is the same thing..

[crock]

It is exactly like that. It will go away from time to time, but come back later. I thought it was from the speakers on day, but it wasnt.

When drilling through the rubber fitting you may have clipped the vacuum hose there. I did the same thing when installing my subs.
