if it lasts a second or two its usually the belt slipping from when the AC compressor starts, but that is more of a squealing sound. otherwise its the sound of the clutch mechanism in the AC compressor engaging, but that really shouldnt make more than an instantaneous sound if any (slight click sound, you wont be able to hear it unless your outside the vehicle).
