1988 4.0 xj

Started my car today, let it sit for a second, then turned on my AC. After about a minute or so, it started making this noise. Any idea why?

Ok, that is indeed a weird noise. Does is go away when you turn off the AC? or change when you adjust the fan speed?

Yes it goes away when I turn it off. I'm not sure about when I adjust the speed though. It also doesn't always make the sound? But it does it alot
