Ok, so a few of you and myself included have the same problem with the fan. It's ok on the high setting but if you put it down to 1 it sounds like the blades of the fan are touching something and it makes a constant squeaking sound that really irritates me!!!

I've avoided bringing it in yet because I have other pending issues and want to get everything done at the same time. (pass. side panel lifting, bezel around the sunroof control keeps falling down) I'm sure something else will happen and then I'll do it all at the same time.

More rattle than squeak.

Same problem here even after it warms up. I am getting a list together of things that are getting fixed under warranrty right now.
1.) Heater fan
2.) Passanger side trim
3.) Rattle in exhaust

I have the sqeaky fan too--on 1 setting. When I go in for my 10,000km check up I will have them fix it. Very annoying

I have it, the dealer "couldn't hear it", and its not bad enough for me to bitch about

I've replaced one in an LS sedan for a squeak under warranty. Not only did I hear it while it was running but after I pulled it out you could hear it by free spinning it and see some rust at the bottom of the motor. It was a PAIN to pull out, they are molded as part of the case and have to be cut out via a razor blade. Funny thing is that they also have the holes molded in to bolt up the new one, go figure.

EDIT- btw- mine doesn't squeak....yet

replaced it a while back

Same problem here. It only does it on the first setting. Sometimes it is hardly noticeable, and other times it's loud as hell. I've thought about bringing it to the dealer. But I've brought my car to the dealer before for other weird noises and they always tell me they don't hear anything.

I thought maybe it has something to do with the air filter in the glove box needing to be changed? I tried getting at mine but was unsuccessful. After dropping the door down, I can't figure out how to get the filter out.

looks to be a common problem, I did what your doing, I got it all done at one time during my 36000 mile check up. It was all done under warranty repair.

betterthanbad

They replace the entire motor and then it does it again about 6 months later!!!

xravenwingsx

mine used to only do it while coming to a stop, now it does it all the time, on any fan setting..... 1, 2, 3, 4--doesn't matter. still does it. kind of like a squeak+rattle. not loud enough to really annoy me yet, though. I'll just get it swapped out before my warranty runs out @ 36K.

trent_ky

mine has started doing it lately it pisses me off to the point where id rather be uncomfortable then hear the piece of ****

jsscooby

Setting 1 makes a weird whistle noise

jeffrieckonfiyaaa

Mine does it too and it pisses me off! So i normally turn the radio up or turn the fan off.

I rought my car to the dealer yesterday, not only for this problem but for a few other noises that I finally got sick of dealing with. The tech that's going to be working on my car told me that he just had another Cobalt in with the same problem and had to replace the motor. He said that GM states the newer motors are better, so hopefully it does the trick.

the fan problem is common (me and others); the sunroof bezel is common(me and others); the sunroof LEAKING (not a whole lot just a little[me]); driver side inside door handle is common (me and others); interior trim chipping is common (me and others); .... man what else? I know there is more... oh ya, exhaust rattle is common (me and others...).... hmmmmmm but for some crazy reason i still like the 'balt? (common... me and others )

Badju587

Haha, me too... I think it has something to do with second gear...

I only have the fan rattle problem, turns into a mini-blower-whine at anything above 2. Probably the motor, I suspected bearings initially but that would have been a nastier sound. If this is the worst I get I'll be happy, the Cobalt is the first american car I've owned with any issues that weren't brought on by operator error (My neon had a problem with the radiator, but that was after I attempted to mate it to the trailer hitch of an F-150 ).
