Hello guys! this is my first post...

I've had my 04 Crossfire for about a year now. It has around 33k miles. About a week a go I started hearing a wheezing sound. It sounds like is coming from the trunk area but I have not been able to fully locate it. You cannot hear the sound after you start the car, the wheezing only occurs right before I start the car (even before sticking the key in) and right after turning it off.

I haven't noticed anything bad performance-wise anywhere else, but the sound is definitely loud.

Any ideas?

Thanks!
