Blower whistling noise

When my heat is on the med to higher speeds I get a whistling noise. I noticed if I turn on the recirc it stops but recirc doesn't stay on very long in auto with the heat going. Anyone else have this?

Great. I just figured out how to fix that problem on my 08 after the dealer replaced the blower motor twice. Planning to trade it on a 14 soon and hope my new one doesn't have the issue you guys are seeing!

I checked and there doesn't appear to be a service bulletin for that issue on the 14s. Hopefully the blower motor does the trick for you. Good luck!

Just had my '14's motor replaced too under warranty. It was making a clicking noise intermittently.

All is better now. Sounds like a 2014 problem though that quite a few users here are dealing with.

My '14 Summit 11/6 build date had a bad bearing in blower motor. It would let out a high pitched squeal only when on highest blower speed (7). Turn down a notch to 6 and it disappeared. Dealer replaced blower motor. Problem gone.

I'm going in fora second replacement. My 2011 WK2 limited had first blower unit replaced at 38K miles. $$100 deductible paid. Now less than 18 months later again I will be paying. I'm kind of pissed and will grill the JEEP people, though I know they can only install the parts they have. I wish an aftermarket part was available as bearings shouldn't fail after it's been noted for years. Poor Jeep follow through on this. Although a common failure with electric motors at high rom and cool temps most companies have figured this out and seal the bearings well so no moisture gets in. That's usually the thing that leads to the breakdown of the bearings to start.

I don't know how they r charging 1100 or 9000 dollars for a motor blower!! That is just highway robbery. Hopefully your not paying that yourself.

I had this same issue. Unfortunately my warranty was up. Went down to my local Jeep dealer, picked up a new blower motor for 95 and I installed the motor in less than 20 minutes. Issue resolved.

Now unfortunately less than 9 months later I had to replace that motor again because of the nearing issue. Thankfully I saved my receipt and they warrantied it at no cost to me. Just annoying to do the whole process again.

My belief behind the bad bearing is due to water getting into the HVAC system and rusting the bearing. My car is an outside car, I don't garage it ever which I think might be the contributing factor.

Just a poor design in either the bearing or the HVAC system. It would be nice to know if there is in fact a correlation between outside cars vs garaged cars and bad blower motor fans

New 2015 HA has the high pitch noise from the blower. Only when it's very cold out and blower is on high. Doesn't last long then it's gone. My 2014 never did this. Not worth it to take to dealer since it rarely does it.

Nope, they say it's nothing more than a cheaply (or poorly) built blower motor. They are actually cheap online so it's really not a huge deal if it goes out. I think I see new ones on mopar sites for like 100-120 bucks new OEM.
