I hear your pain. I have a 01 QC 3.9L auto and live in northern Alberta. Whenever the temp gets colder than -10 deg cel, I also get the high pitched whine, and also thought it was coming from the dash. The actual problem is that the crown and pinion gear in the rear end is slightly out of alignment/sync/whack or whatever you want to call it. I had mine in here at the dealership, and the mechanic explained the problem. They were shipped from the factory like that. He also said I was lucky, because he's heard some that are so loud you can't carry on a conversation in the cab. I bought my truck in the summer (June of 01), so I didn't notice it until the following November. It's covered by warranty, so Dodge will pay for the whole thing. I haven't had mine fixed yet, but I will. It doesn't seem to have a detrimental effect in the short term (except for that damn whistle/whine), but I'm sure 50K after the powertrain runs out, the rear end will blow out in a big way.
Hope this helps.
Victor

Sorry, what I meant to say was "I'm sure that 50k after the powertrain WARRANTY runs out, the rear end will blow out in a big way". Let that be a lesson. Proofread.

I have the same problem with my 2003 Dakota. My warranty has expired, so I guess the only option here is to take it back to the dealer and pay them to fix it?

It could be possibly in your alternator system. When it gets cold sometimes parts tend to not work as well. I have a 1994 Dodge Dakota with that problem it works fine but the alternator whines a little bit.

This post is really good news...or bad but I am too suffering this odd high pitch whine on my 2001 Dakota 4x4 (I'm going to make a small AVI and post it to UTube cause I've tried to mention this before and had a billion answers from peeps that I can't really explain too).
This whine like you said starts here in Northern Ontario from October(ish) through to April! When of course it's at or minus 0 degrees. The whine is really hard to pinpoint as I've tried alot too because it's one of those pitches that resonates from everywhere you move your head. Annoying as hell I'll add!
I'm not liking what V-Man posted above and I have to agree that it's sounding from the dash/front area...atleast now I'm really really hoping! It's controllable with a slight movement of the throttle and winds down quick like as if it's a belt whirring down to silent but it's definately not a manual belt(ish) sound...it's like those annoying deer whistles mounted on bumpers.
I had a warranty that recently ran out...bah. Can anyone add a fix/suggestion to this post.

Rockin Rog, that describes my high pitch whine to the 'T'. Only when it is cold, and can be suppressed by releasing the throttle.
Anyone know what the problem is?

I have exactly the same problem as Rockin Rog and foobish. I live in Markham. I have mentioned it to three different dealers and each emphatically denies every hearing of this problem.
I think it's an air leak somewhere but I have no clue as to where you would look.

What you have described is exactly the same thing that's happening to my '02. It only happens when it's cold -10 or under. I took it to my mechanic and he heard it but said he had never heard anything like it before in his 20+ years in the trade. I'm hoping it's in the pulley system, at least that should be a cheap fix. Otherwise I'll have to start driving with earplugs all winter!!

Try taking the belt off and see if it goes away.

Who here with the high pitch wine problem runs a K&N air filter? Or any other high flow air filter? (Airaid etc.)
Im guessing everyone with the whinning...
Dont know why, or where it comes from but my truck whines like mad with a high flow air filter in it, and silent without one.
Try a regular filter and see if it goes away.

I went ice fishing in some of the coldest weather this winter. -25f When you would wake up. Some days it didnt make it above -5. -60 degree windchills out on a giant slab of ice. I too have a whirling whining sound when its cold. This must just be normal. Youd whine too if you had to haul around almost 5k lbs in subzero conditions. : )

Has anyone figured out the answer to this yet? Got a 2003 Dakota with the exact same problem that no one up here can figure out. It is driving my GF completely nuts. I think I can safely say that anyone here who thinks that this noise is "normal" has not heard this particular noise. THIS noise sounds like banshees of hell screaming to get out from under the hood.

My guess is speedometer cable under the dash, when its cold all my daks make a squeeking and it seems to be the speedo cable cause it doesnt squeek in the summer.......thats just my two cents.

Hi Bucket. That's a good guess but if it is a noisy speedometer cable, the noise should be there at very low temperatures whereas this noise only occurs close to the freezing temperature of 30 degrees Fahrenheit. I've has noisy speedometer cables and lubrication solves it. This whine is a continuous shrill whistle that sounds similar to that of a Boy Scout whistle (only it doesn't stop to take a breath).
Thanks for the suggestion and keep them coming.

I too am experiencing this noise. I own a 01 Dakota, and I have been experiencing this noise off and on since October. If it was continuous it would drive me nuts. I'm just happy to find out other people are experiencing the same thing. I'll keep a close eye on this sight for a solution.

ok so if you have replaced the iac u know that there is an O-ring around it. i have "heard" that the ring hardens in cold weather and allows air in causing the whistle. the solution is to put it in with a little high temp silicone and seal er up.
