OK. Here is the problem... I have a 08 sedan lt and when i turn on the a/c or the heat on low it makes noise i dont know how to explain it but it is anoying as HE**. Since you all have been so great before do you think that you could provide me with an idea on what it might be?? It is still under waranty but i would kind of like to have some feedback from others first. And maybe help someone else that is having the same problem...

Does it sound like some sort of ticking? or is it just the engine kind of droning. Because whenever I turn on my AC or heater it puts a little more load on the engine causing somewhat of a drone effect. But also Sometime i can hear a kind of "tick" for that I think there are leaves or something caught in the fan.

it could either be your blower fan, or your AC compressor clutch......... without hearing the noise, couldnt tell you exactly what it is

Check your blower fans then, cause i may not have a cobalt, but i get it now that i replaced my fan on my car.

Had this problem on setting one and two. changed blower a few weeks ago and its all good.

Note factory blower needs to be cut out and then replacement gets screwed in with a gasket. Had mine done under warranty

I have that too. If I put the heater on 3 or four first and then go back down to 1 or 2 I don't hear it, but if I just put it on 1 or 2 first, it's there. It may still be under my warranty, so I may just get it checked out. =)

Yep thats exactly how mine was Jeliza. Go get it done if you still have warranty. The new updated blower is stronger too.

I had to complain real hard but they did do it. I exaggerated cause originally they said they couldnt duplicate it so I told them that it gets worse when driving for a long period of time and that if they wouldnt do it I would be calling head office to tell them to do it. Just a heads up.
