It has been three years since I bought my SLOBALT, and now there's pretty much one thing annoying the crap outta me.

My climate control fan makes this ridiculous squeak. It kinda sounds like crickets. The only remedy for this is to run the fan on a speed higher than "2". I don't like to run the fan that high for a drive over 10 minutes, cuz it just gets to airy, and in the winter time, too hot.

When I turn the fan off you can slowly hear it wind down, and it sounds like the squeak is per-rotation of the fan. It's loudest at level "1", and a bit less at level "2". Around left corners it gets much louder, and around right corners it gets a little quieter.

It seems like it could just be the bearings on the fan, so I'd like to get in there and try to lube it up a lil bit. So my dilemma is I don't know exactly where the fan is. The noise is definitely behind the glove box region, so that's a start, but it will be much easier for me to access the fan if I know exactly where I'm looking.

If anybody could give me some sound advice in how to access the climate control fan, and service it, that would be great.

ETA: I found this thread https://www.cobaltss.net/forums/show...700#post700700 Which looks like the exact same problem, sadly nobody had answers for him either.

 

Both of my cobalt's have done this, it annoys the hell out of me. The worst part is that both of them have done it since new.

 

My new 09 SS does it, and my 06 did it.

I know a bunch of people with the same problem and GM never bothered to fix it.

Most dealerships replace the face and lube it some how.

 

my 05 SC has been doing it since late 06 trust me after a while you will get use to it...get cold...or get hot ha ha

 

mine does it so loud id rather not have heat

 

my 07 SS does the exact same thing. And you are right it does sound like a box full of crickets being viciously shaken.

 

have you guys tried to see if there is something that has fallen down in the fan blower motor? fixed my problem really fast... probably need to change your cabin air filter while your in there.

 

mine sounds like a playin card in the spokes of a bikes wheel

 

whats a "van" lol :P

and yeah i have the same exact problem with mine, i just suck it up and crank it to 3. lol. then when it gets warm enough i just turn it off completely and warm air still comes out of the vents.

 

Ugh, well its comforting knowing that this is a problem.... I guess. But it sucks that nobody knows how to get at it. I guess I could just start ripping off interior panels and try to find the fan. I'm at work till 5, so somebody try to get some motivation, and tear into ur car, and find the problem!

 

sigh.... I have that noise too..... annoying.... What I haven't tested, is if it is only on the dash vents, or if it happens on defrost and floor....

 

This is a Van!

sounds like it needs a lube job. sounds really like a bushing is loose or missing that is letting it shift around on the shaft, which makes it loud on left hand turns. id take down the blower motor and check it out

 

could just buy a fart can exhaust and drown the noise out with 3rd gear drone all day long

 

i guess i will post that again since no one really payed attention. its behind the glove box, just push in on both sides of the glove box and it will drop it out and the cabin air filter is behind the panel.

when you take out the filter try to feel around to see if there is a leaf or something that will be a noticable obstruction. there is many cases of rats making a nest on top of the filter.

If it continues to happen, you can get under the dash and take the blower motor out. have fun.

 

If I took out my cabin air filter and a rat popped out i'd **** myself

 

i've got the same damn problem. didnt start till about 3 months ago and i also ended up with a leak somewhere in my floorboard. sounds like a bad blower motor

 

Hmmm, I have a 06 SS/SC and an 07 SS/NA, both bought brand new. Neither have this problem.

 

Alright, I changed all the "vans" to "fans". So most suggest checking out the blower motor.... OK. Just like a 3 step process of the best way to access that would be great.

 

ive opened air boxes fo find kittens living in there, snakes around intakes, and once had a cat jump out at me as soon as i opened the hood..

2 techs took the cats (camry and tacoma became their names cause thats what cars they came out of) and no one knows what happened to the snake

 

/\ Like, wtf man

 

bump...because i'd like to know how to fix it too

 

I had this problem as well. It sounded like crickets coming from the passenger fan. It was actually the blower motor underneath the glove box. It had leaves and junk in it (Cabin air filter dirty). I got the blower motor replaced under warranty and replaced the cabin air filter and now its fine. im at 3 years 36,500 miles.

I was told you can open it up and clean the crap out if I wanted later on. It seems very easy to access. hopes this helps.

 

Recently took my car in for this and it turned out to be a bad fan bearing that was coming apart. They replaced it under warranty. Since they did it though, I don't know what they did specifically to get to it, so I can't offer any tips on that. The noise is completely gone now though, so that was for sure the cause.

I had previously cleaned out the cabin air filter and all up in there and although I found a leaf and normal dirt, the sound stuck around after I cleaned it all up. It would sound like you all described on Speed I. Speed II would make it go away a little bit and above that I couldn't really hear it.

 

You're lucky

 

I have never had a problem with my cobalt...i have 78,xxx on an 06 ss/sc with a GM stage II, CAI, Fidanza flywheel , clutch , and no cat
