I have a high pitched noise coming from my HVAC blower motor on cold starts. The problem occurred at the end of last winter and went away when there weather turned warmer. Now that we are in winter again, the sound has returned.
It comes from the passenger side area under the console and last for aboutnfive minutes. Once everything warms up the sound is gone. Any ideas on the root of my problem?
I had a similar issue with my blower moter that turned out to be a bad bearing. It was replaced under warrantee. The issue was not temp. related though, as it happened all the time. Check out this thread;
Has anyone found a good aftermarket blower? My 2011 JGC Overland has the blower whine mentioned on this thread. I'm about to replace it on my own and out of pocket (mine is out of warranty)
I just want to do this ONCE so I'm looking for a more reliable part than the OEM version that people are having to replace every 10-30k miles...
Any suggestions?
Has anyone used an aftermarket blower successfully???
I have the bad bearing noise as well. I should get it checked out. If I drive down a rough dirt road nearby, sometimes it fixes it. Usually the homegrown fix is volume control on the radio.
Do you know exactly what they did wrong? I recently replace cabin air filter myself and had this problem. I don't think I did it wrong and the arrow on the filter was pointing down as it was supposed to.
I sometimes experience this now. It started about 2 weeks ago when I replaced cabin air filter myself (it was not as easy I expected). I don't think I did anything wrong but it seems to be less noticeable after a while.
According to others my 2012 made the same noise. I couldn't hear it and it was rather sad that the service writer (who was older than me) said he could hear it clearly. The blower motor was replaced under warranty. I guess it's time to have my hearing checked.
I am going for my second replacement for the HVAC blower as the bearing are going and the unit makes the noises, especially when it's below freezing outside which makes things contract just a bit more. I would think Jeep would get this problem sorted out as this is apparently a known flaw. It will cost me my $100 deductible in my extended warranty and I'm quite frustrated.
I also have a 2011 JGC (Laredo) with the same HVAC blower motor noise. I'd brought it in a while back and they mentioned that the motor needed to be replaced, but I felt the $600-700 repair cost was absurd. Naturally, I would like to do this myself instead.

Great info. This is a poorly designed blower with bearings that will go out almost every other year if you are in an area with low Winter temps and warm humid Summers. I have no more $100 deductible extended warranty, so I will be ordering these next time unless I can find an alternate supplier than fixed the roller bearing issues. It shouldn't be a hard thing to correct using powdered graphite or an alternate bearing design. I've have had 3 in my 5 year old WK2. Ridiculous.
I have 60k on my 2014 and have replaced the motors twice. Both out of warranty of course.
First time I replaced it with a mopar part, and it only lasted 6 months before making noise again. Most recently replaced it with an aftermarket unit from rockauto.com and it started out with a high pitch noise at high fan speeds which went away with use. Not that it is getting cold here (in the 50's) the motor is making a squealing noise on low fan speeds. I really can't win with these damn motors.
Any one take them apart yourself and relube the bearings??
Just traded in the WK2 on a 2016 Trailhawk. I hope to have better luck with less automatic stuff other than the cold weather package with heated everything. Looks good as a Lava Shark.
Please do not let the HVAC blower issue follow me. So far its nice and looks great.
Best of luck gents.
