Not sure if i should have posted this here or not but I guess it has to do with interior. I have a 2003 Sunfire coupe and when i have my fan on inside I can hear engine whine through the fan. Its hard to explain the sound. The noise varries with engine rpm. Its the lower rpm's when its really loud. As rpms climb the engine noise over powers the fan. When the car is at idle the fan kind of makes a chirping noise. I have no idea what it can be but its driving me insane. When i turn the fan off the noise goes away. Any help would be awesome.

Thanks

my buddy had a similar problem, turned out to be a loose belt connected to the A/C, might wanna check that

Thanks for the reply but I don't have AC in my car. Any other ideas?

Anyone else this is really driving me nuts!!!!
