THISCONDITION CAN IN TURN LEAD TO POSSIBLE FRACTURE OF THE POWER STEERINGPUMP MOUNTING BRACKET AND/OR LOSS OF THE SERPENTINE ACCESSORY DRIVEBELT. LOSS OF THE DRIVE BELT WOULD RESULT IN LOSS OF A/C, GENERATOR,POWER STEERING ASSIST AND WATER PUMP OPERATION.ANALYSIS: THERE ARE NO REPORTS IN THE ODI LETTER FILE REGARDING THISPROBLEM.ALTHOUGH G.M. HAS 153 COMPLAINTS, MOST OFWHICH ARE WARRANTY CLAIMS, ONLY TWO ACCIDENTS HAVE BEEN REPORTED THATWERE ALLEGDLY CAUSED BY THE FAILURE OF THE P/S SYSTEM.
