Alright Goat experts... REALLY need your help right now. Back in mid May I had the A/C Belt tensioner, A/C Idler pulley, A/C belt, main belt all changed. Got rid of the the noise. Right after this my good friend who is also a mechanic called me up to the shop. There was now a whistling/squealing type noise. Thought maybe the belt was breaking in, just guessing to make myself feel better. Caught it on my phone making the noise. Another well known mechanic in my area didn't know. Like I said, it comes and goes. Completely random whether it's hot/cold, day/night. Recently I have started pulling into one of those spray off car washes, opened my door and recently it's been there. Once I turn ON the A/C the noise completely goes away. Tonight same thing. Had the defrost on low power, turned on the A/C button, goes away just like that. Seriously will someone please help me because it is driving me nuts and it's pretty embarrassing driving a car that is making a very loud and annoying noise. But yeah, PLEASE... any input would be much appreciated. This is just discouraging.

If it's a belt squeal issue, I'd steam clean the front half of the engine and buy a new belt. Make sure the belt is soft n supple; don't get one sitting on a store shelf for 5 years. Gates was a worst offender for this on one of my cars. I had to replace a new belt with an oem version that had a flat look to it. The gates became all polished up too quickly and sounded like ****.
I'd also check alignment of everything while you are in there.

Thanks for the quick response. Much appreciated my friend. I will definitely look into that. If my buddy isn't busy I may just swing it up to his shop tomorrow. Have you ever heard of that though?!?! The noise going away when you turn on the A/C??? It's seriously my luck. I love this car, but just have not had good luck.

What Mike said. Look at alignment. Look to see if your harmonic balancer is doing the hoolah and moving more than it should be.
For good measure, remove serpentine, inspect both tensioner and idler pullies. Easy stuff. Takes 10-15 min to assess all this. If you weren't in MI I would hook you up!
Let us know what you find.

I had that problem on a Suburban once and it turned out to be a bad alternator, sounded just like a belt. I replaced the tensioner twice, the belt and even took the a/c belt off thinking that was it. Alternator went out one day, replaced it and the noise was gone.

Yep. I cut the AC belt off because of noise. About 8 months later I put a new on on because it was getting really hot and... no noise at all. The old belt was new, I had changed it because of the noise in the first place. So what cured the issue? Who knows...
Good luck OP!!! But I drove the car for well over a year without the noise coming back!

Take off the main belt and start the car. If the noise went away, then the problem lies with the main serpentine accessories. If the noise didn't go away, then the problem lies with the AC accessories.
You can also get a mechanic's stethoscope and listen to each pulley and accessory to try and pinpoint the noise.

Man... can't thank all of you enough for the suggestions/help/advice. The belts pulleys etc turn out to be fine. Like I had mentioned earlier my very good friend works at the shop, well his dad who owns the shop, drove it etc. I told him how it goes away when I turn on the AC. And he couldn't say AC Clutch fast enough. Has anyone had theirs go bad?
