Unexplained noise w/ 2008 Range Rover S/C
 

I recently purchased a 2008 Range Rover S/C, which I absolutely love it. However, I have noticed 2 very distinct noises that the dealership cannot seem to explain or provide a solution as to how to fix the problem.

Problem 1) There is an incessant howling noise when driving into a strong headwind which seems to be emanating from the windshield area. I took the car to the dealership, but of course, there wasn't a strong wind to help replicate the noise and they claim to have never heard of the problem before.

Problem 2) When the fan is on there is a low pulsating/humming noise that is constant along lower driver-side next to the steering column. The noise is definitely tied to the fan because it goes away when I turn it off.

The dealership seems stymied by the noise but said that it was common with other 2008 S/C models they tested. The noise is rather annoying, especially if you are not running the radio. I had a 2009 Range Rover Sport HSE and have never had a problem with fan noise. Any thoughts?

Thanks in advance for any suggestions you might have.

Number 1: Might be your wipers or a seal leak. Duct tape is an easy way to narrow down culprit.

Number 2: Is it when you have your cooled/heated seats on? If it is unrelated, it could be a blower motor. Our Escalade does this when you turn the seat temp controls on...

Thanks for your input. It appears that the seal around the windshield might be loose. The blower problem exists even when the heated seats are off. Its a very bizarre sound that almost pulsates at a low hum and stops when the fan is off. I can accept if the noise is simply part of the vehicle's standard operation but I've never had a vehicle where a fan noise could be so annoying. You would think with a luxury SUV that regardless off its "off-road" reputation that the finer appointments would include a peaceful cabin.

to fix the wind noise get some closed cell rubber foam from ACE hardware and fit a piece under the trim around the windshield you might only need a thin piece this will stop the air from moving under the trim and making noise.
The fan noise sounds like a portion of the fan housing is touching an adjacent part and transferring the vibration it may take some dash disassembly to find this

I have an '07 Supercharged and I have never heard a fan noise as explained. I would definitely try to convince the dealer to investigate.
