chirping sound?

[todd11231]

When I have my A/C on and around 2k rpms i hear a chirping sound comeing from under the hood. Anybody know anything about this? doesnt always do it...and it goes away pretty quick. I would take it in but i know it wont do it with the guy there. especially after i drive it over there. If anybody knows anything about this i would appreciate you help. Thanks
