My 4Runner makes a squealing noise when my A/C is running.. toyota dealership said its just a common 4runner issue and they don't fix it...? Any idea how I can get rid of this annoying sound or anyone have similar issue?

What year truck? If you've got an idler pulley on the verge of going bad, the added load of the A/C compressor can cause that pulley to squeal. It happened on my '08.
