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?

Re: Blower whistling noise

I'm experiencing the same thing. After 3 trips to the dealership, I finally talked to the service manager, and they are replacing the blower motor for me.

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!

Re: Blower whistling noise

Apparently this is a common problem. I had my blower motor replaced under warrantee (2012 Summit) for a failing motor bearing!

Re: Blower whistling noise

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.

Re: Blower whistling noise

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.

Re: Blower whistling noise

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.

Already beat you to it! Had the replacement replaced 6 months after first. About 9k on each.

Re: Blower whistling noise

Anything that Jeep suggested as to get a better product without this Achilles heel?
