The last week or so I have been having a faint noise from the engine bay and I believe it is the a/c compressor but wanted a second opinion from you guys. The a/c still blows cold but randomly sometimes will give me a rattling or a chattering sound from the engine bay. almost sounds like a loose bolt. It also only makes noise when I have the A/C on and doesn't make a sound when I turn the A/C off. any insight would be great. Thanks!
