I have a 2003 blazer LS 4x4 I have replaced the air conditioning compressor because of a bad pulley bearing, Idler pulley same reason, belt tensioner and belt. The rest of the pulleys are fine and no wobble and seem to spin just fine. But now I have a chirp only when the engine is cold stops when warm. Also while chirping can spray water out of a spray bottle on belt any were and chirp stops temporary. Can any one help me with this chirp that is driving me up a wall.
