check your alternator and also the AC compressor. I hit a bad puddle one day in mine, and the following day I had a whine that resembled the noise of a failing alternator. I narrowed it down to the AC compressor and i bypassed it for now with a shorter belt.

this may sound silly , but anything i can spray to maybe give it as a temp fix for a week or 2,
wd-40 or something ?
i just simply dont have the time to fix it but dont want anything to break...

If it's a high pitch squeal then it's likely the belt just needing to be tightened. If it's more of a metallic whine/hiss noise then it's the compressor. Not sure what model year yours is, but if it's a 97-99, I can give you the info where you can get a remanufactured one for $175+shipping. Great seller and it's $150-200 less than autozone or advanced remanufactured ones. I think I got the last 95-96 he had, but I can check with him to be sure if needed.

but it doesnt change when i turn the ac on or off....??
still the compressor?
tried spraying everything ith wd but it didnt help....

I forget which model (97-98) It was but If I choose It was a 98 with the alternator problems or recalls. I am sure this Is the symptom of a bad alternator and It's probally on it's last legs.

Does the whine sound like a faint s/c,If so It Is more likely the alternator and It's about to go out on you.

It could also be the a/c idler pulley assembly, I have a whinning noise as well on my maxima and I just recieved my replacement idler pulley. I will be putting it on tomorrow I will let you know if that takes care of the whinning noise.
Good luck with the new car and enjoy.

Take a long pole and stick up against alternator see if you here the noise go through the pole. Then put it up against the compressor. My old car was making a whine from the alternator even though it was still working fine and it sounded like I had a S/C. I got it replaced just in case.
#15
check the alternator, best way is to take off the belt start the car see if the noise is still present but i had that problem on my 96 and 99 max made whinning, hollowing n noise before it went on me. My brothers i30 has that problem now just have to change the alternator.

Wow. I had this happen last night for the first time. Totally sounds like a faint supercharger too. Am glad I found this thread. I'll do the screwdriver to the ear listening method, but it sounds exactly the way maxspeed96CT described it.
Any suggestions on the best/cheapest alternator? Should I buy only Nissan parts for this, or is it a Kragen/Checker/Shucks special?
I had a bad experience with a Kragen alternator on an old Acura once.

I just got this whine today. Was odd, I drove to the supermarket and it was running normal then I get out and go to drive home and the whine started as soon as I started it. Struck me a little odd that it didn't build up over time, it just happened.
I haven't had the chance to check and confirm it's the alternator, but it was my main suspect even before I looked at this thread. Mainly because my headlights don't seem as bright as they once were. I'll be popping the bonnet tomorrow and seeing what I can find...
