Weird in-cabin noise

Mensaf · #1 01-31-2009, 11:51 AM

I hear this more at low speeds, and sometimes it doesn't start (or I don't notice it) until it shifts. At first I thought it was either the speakers or the blower motor making the noise, since it sounded like an electrical whine of sorts, but when both were off the noise surfaced. I then thought it could be a belt or pulley, but they're all in good working order and there is no noise from the engine bay. It seems as though this whining noise also increases with how far down the throttle is depressed. Any ideas?

Describe it more... Is it like a squeaking/squealing? Sounds like it's coming from the passenger side?

It SEEMS like it could be, but there aren't any vaccum lines within, are there?

there should be in the dash that open and close the vent doors . that direct the air to diff vents in your car they are vaccumed controled. i think?

The air path for the HVAC is electrically controlled with motorized levers.

Get's noisier with throttle... could it be a hydraulic oil noise from the trans?

Nevermind. Waterpump

What are the odds of Autozone having that, the belt, and all in stock tomorrow?

3 out of 10 my guess

Not so good.... and also you may want to get a new timing cover gasket set as well.

Water pump? Wasn't my first guess but was a close second. Glad you figured it out and hope it is fixed soon..

I wouldnt really recommend the autozone parts when it comes to the cooling system. I had a sticky thermostat that wouldn't open at the correct temperature, and i had to drain everything and refill 3 times before finally installing one that worked.

Yea, just waiting on the parts as of now. If I had the time, I'd change the head gasket while I'm at it just for peace of mind. I've been going back and forth between selling the car for something more tuner/budget friendly, but it's slowly starting settle into a more long term spot in my driveway.

Ordered my stuff from the dealer. Price difference wasn't much.
