Re: HVAC Fan Noise

Mine is at the dealer right now. It makes a sound like something is hitting the fan blades and it barely blows out the vents, when the noise stops then it returns to the set speed.

Re: HVAC Fan Noise

We just picked up a Laredo X and only when we first start the vehicle or turn on the a/c we get a whine coming from the passenger side front. First time I heard it sounded like a little girl screaming. It only last for a second then goes away. Problem is it doesn't happen all the time so I know when I take it back to the dealer they will not be able to replicate it.

Imagine holding a piece of plastic against a house fan - or for your IT guys, it sounds just like a wire against a case fan. Unfortunately it went away after a minute (and some banging on the glovebox and kick panel). Then later it came back again, then went away again. It does not sound like bad bearings, definitely like something hitting the fan.

Now I know I could take it to the dealer but I hate going to the dealer for stupid crap - especially when it is intermittent and might not manifest itself when they have the truck. Too many times I've spent the day shuffling around without a car and they 'can't reproduce the problem'. So what I'd like to know is (1) Has anyone else had this issue - if so what was done about it and (2) Is it possible I can remove a few interior panels and get at this fan myself to remove whatever is hitting it? Or is this something I would have to remove the whole dash to get at? Thanks!
I actually have that same noise coming from the bottom of my glove box. You can actually remove the fan that is making the noise with just a screwdriver. All you need is to remove the bottom cloth like cover and you will see the fan. Remove the three screws and you will be able to lower the fan. Obviously make sure your fan is off. Once of, be careful but you can turn the fan on while holding on to the base and you will hear the noise coming from the fan. It seems the blades are of balance on mine and that is what is making the noise.

Just took mine in for a rattle in the vent and they said a label from the duct came loose. They fixed it under warranty of course. Pathetic, putting labels in ducts!

Re: HVAC Fan Noise

My problem turned out to be a malfunctioning actuator replaced under warranty. Service representative said that it is common on the Ram but not the Grand Cherokee.

Re: HVAC Fan Noise

This just came up yesterday for me. Had the AC on and all if a sudden this clicking/slapping noise started coming from the glovebox area. Along with that came the fan coming to pretty much a halt. 43k miles so Im calling the stealership. I had noticed back at 34k miles that the blender doors weren't working right. When in auto and bi sides in sync the driver side was by feel 5-7 degrees cooler. They said it was normal. I'll be trying to tie it into a faulty HVAC. Best of luck all.

Re: HVAC Fan Noise

I am currently having the same problem in my 2012 Wrangler Unlimited. I discovered that it is an easy job to remove the blower assembly so I removed it and did not find any leaves or other debris. I also turned the fan and none of the blades were bent or missing. I reinstalled it and did not hear anything until the next day.
Anyone have any updates on this problem?

Re: HVAC Fan Noise

Well, long story here. Been fighting with Freehold Jeep about this issue since 15,000 miles (now currently have 28,000). They told me it was normal noise which is BS because my buddy has one and i compared both blower motors. Service manager basically told me to not worry and just "enjoy" the truck. Too bad for him, i'm going to be on the phone with Chrysler about the stuff i've put up with them about for the past year. Absolutly hate this dealer. Mine has been getting worse and worse every day now. Took it upon myself to take the blower motor out (i am a mechanic lol) removed the felt panel under the passenger side dash by where your feet are, make sure to unclip the connector for the little foot light, took the 3 little torx screws out and unclipped the connector and it came right out. Pushed against it in my hand and turned it manually and it feels like a bad bearing. Going to go to buhler jeep which i have never had a problem with to get this issue resolved. Freehold was basically pushing me away until my 3 years, 36,000 mile warranty is up for bumper to bumper. No way i am paying for this.

Re: HVAC Fan Noise

Rehashing an old thread here, but same problem happened to me over the holidays.
Clicking noise could be heard from near the glove box (wife described it as having a box of hamsters hidden in the glove box)

Brought it to dealer today, took about 5 seconds to diagnose--bad bearings in blower motor. Part ordered and will be installed tomorrow. Dealer says in/out in about a half an hour.

Re: HVAC Fan Noise

I thought that I might add to this old thread. My 2011 Overland also developed the fan noise issue around 35K miles. I dropped the blower, expecting to find debris or an obvious bearing issue. I noticed that the bolt that holds the fan to the housing was extremely corroded. So corroded, in fact, that I had a hard time determining if it was actually a hex head that I was looking at. Obviously, some water is getting by the in cabin filter. My guess is that the corrosion traveled down the bolt, and began to affect the bearings.

Only about 15 minutes to drop the blower, and 150 for the new part. My GC is covered under the extended warranty, and I had it replaced at the dealer yesterday. All is well, but I think it will most likely happen again, unless the water issue is addressed. My plan is to drop that blower again, and coat the top bolt hex in either a lithium grease, or maybe even a glob of silicon sealant to prevent this new part from corroding. Has anyone else noticed this?

Re: HVAC Fan Noise

I bought a certified used 2011 WK2 and after a couple of months I noticed a consistent buzzing sound coming from the HVAC fan. Just loud enough to be irritating when you have to listen to it every day. You can only really notice it when the fan is running with 2 bars showing on the fan display (manual mode). The problem is, that's the speed the fan normally settles in on when the HVAC is in auto mode. Doesn't matter if the AC is on or not. As long as the fan is running at that speed you hear the noise. Been to the dealer twice so far where they performed TSB 24-007-11 and then replaced the blower. Neither fixed the problem. Going back in again today for another try. They’re thinking duct this time. We’ll see.

Re: HVAC Fan Noise

When I went back to pick up my truck after the third visit- the ticket said they took the fan assy out, checked the compartment and put everything back together and the buzzing was gone. When I talked to the service manager, he mentioned they actually found some rust on the fan assy and once they cleaned it off the noise went away. Makes me wonder if they ever actually replaced the fan assy when they said they did. If it was a rust problem on the fan somewhere (wasn't clear where), the noise should've stopped when they replaced the fan assy on the second visit. At least all the work was done under warranty and the problem is gone, but not looking forward to when my warranty runs out.
