Constant Whining Coming From Fuse Box

Hi guys,

I have an '09 GT. I got home from work and I noticed when I walked by my car there was a constant whining noise coming from the engine. I opened the hood and it's coming from the fuse box. What could this be? Car seems to be running fine although I have been having an ac issue where the compressor takes like 2 minutes to kick on which I know I need to get looked at. But it's never done this loud whining. I just went and checked and it's still continuing. Any thoughts? Thanks!!

Haha! Yep so turns out it was the ac clutch relay. I've just never heard a relay or fuse make a whining sound like that before. Replaced it this morning and Io and behold my air conditioning is working normally again! Man I was so worried it was a compressor issue and was going to be costly. Can't believe all this time just a bad relay.
