Hi guys have this problem which is whenever I'm not accelerating I have a rattling sound from my hood.i narrowed the problem to my AC compressor because whenever I turn my AC to zero the noise stopped.The noise will stop for a few sec once in a while.i seriously have no idea what's wrong and hopefully I will get a answer here whether it can be self fixed or do I need to send for a AC compressor replacement.below is the video,thanks in advance.

The reason the noise cycles is because in normal operation, your AC compressor cycles on and off (it doesn't run continuously despite the A/C light being on the car.)

Mine made that noise, and I now have a dead AC compressor. Hopefully, I'll be laying hands on a salvage yard one, and I have the tools to swap it out and recharge the system. Sorry to be the barer of bad news, but it sounds like that may be your issue.
