take a new unworn belt and hold it up to the grooves on your pulleys. Look for any that are worn (ribs don't touch all the way to the bottom of the grooves).

No all runs off one serpentine belt...belt squeal didnt come back until i added freon to line and started using the a/c. I really have no idea what it could it was running quietly for a over month now its back squealing,the squeal does die down just a bit after engine heats up but its definetly there.

I guess I have to park it again, sad part is I thought maybe the tension might be lose so i ordered a oem tensioner from the dealer but that didnt do anything so now im out $95 dollars for the tensioner which i guess wasnt the issue.

Yes and no, at first it would die down once you turned the a.c off but now that doesnt make a difference, Im wondering if the pulleys are glazed and maybe the humiditt caused the belt to pick up contaiments. Im really stumped here and im not looking forward to buying another belt for 80 dollars.

Short and sweet I dont know where to look at this point.
