ON FOUR OCASSIONS I HAVE HAD COLD AIR BLOW OUT OF MY HEATER AFTER THE ENGINE TEMPERATURE GAUGE WAS OVER 100 DEGREES. AFTER CONTIUOUSLY MOVING THE CONTROL KNOB ON AND OFF, EVENTUALLY, SOMETIMES AN HOUR LATER THE HEAT COMES ON. THIS JUST STARTED TO OCCUR THIS YEAR. BY THE TIME I WAS ABLE TO GET TO A DEALER THERE WAS HEAT COMING OUT AND THEY COULD NOT FIND ANY PROBLEMS. WHEN THERE IS COLD AIR COMING OUT, YOU CAN DEPRESS THE "FLOW THRU AIR AND AIR CONDITIONING" BUTTONS AND THE LIGHT ON THESE BUTTONS DO NOT ILLUMINATE. WHEN THE HEAT COMES BACK ON, THE LIGHTS ON THESE BUTTONS ILLUMINATE. I HAVE TOLD THIS TO THE DEALER BUT THEIR "DIAGNOSTIC" CHECK, AGAIN, SHOWS NO PROBLEM. IT APPEARS TO ME THAT THIS COULD BE AN ELECTRICAL PROBLEM OR A BAD SWITCH. JUST THE OTHER DAY, TWO DAYS AGO, WHEN THIS LAST HAPPENED, I HAD THE RADIO ON AM AND WHEN I MOVED THE HEAT SWITCH FROM "OFF" TO "ON" THIS CREATED STATIC ON MY RADIO. *AK

THIS INVESTIGATION INVOLVES THE GENERAL MOTORS CORPORATION (GM)THROTTLE BODY (TB) UTILIZED IN MODEL YEAR (MY) 1999-2002 SILVERADO, SIERRA, TAHOE, SUBURBAN, AVALANCHE AND YUKON (SUBJECT VEHICLE(S)) WITH 4.8L, 5.3L, AND 6.0L ENGINES. THE TB VALVE MAY INTERMITTENTLY STICK IN A CLOSED POSITION.IN SUCH A SITUATION, AN OPERATOR MAY APPLY ADDITIONAL ACCELERATOR PEDAL FORCE TO INCREASE ENGINE SPEED.THE APPLICATION OF ADDITIONAL ACCELERATOR PEDAL FORCE, TO OPEN A STUCK THROTTLE VALVE, MAY OPEN THE THROTTLE VALVE MORE THAN INTENDED AND, IN TURN, ACCELERATE THE ENGINE AND VEHICLE MORE THAN INTENDED AND REASONABLY EXPECTED BY THE DRIVER.ON AUGUST 1, 2002, THE OFFICE OF DEFECTS INVESTIGATION (ODI), OF THE NATIONAL HIGHWAY TRAFFIC SAFETY ADMINISTRATION (NHTSA), OPENED THIS ENGINEERING ANALYSIS.THE INVESTIGATION REVEALED THAT TWO FACTORS MAY CAUSE THE DEFECT: 1) TB MANUFACTURING PROCESS PROBLEMS; AND 2) ACCUMULATION OF DEPOSITS (A PCV SYSTEM BY-PRODUCT) ON OR AROUND THE TB THROTTLE VALVE AND BORE.ODI CONCLUDES THAT THE TB PERFORMS IN A DEFECTIVE MANNER AFTER ANALYZING GM?S DATA SUBMISSIONS, AND TEST DATA COLLECTED BY THE VEHICLE RESEARCH AND TEST CENTER (VRTC).FIFTY-NINE CRASHES ARE ALLEGED TO HAVE OCCURRED AS A RESULT OF GM?S TB DEFECT.THE MAJORITY OF THE CRASHES INVOLVE A SINGLE VEHICLE, ENGAGING IN A CLOSE QUARTER VEHICLE MANEUVER (OR LOW SPEED), AND CAUSING ONLY MINOR PROPERTY DAMAGE.FOUR OUT OF THE FIFTY-NINE CRASHES INVOLVE INJURY, AND THOSE INJURIES WERE MINOR.ALTHOUGH GM?S TB IS DEFECTIVE, BASED ON THE EVIDENCE GATHERED, ODI HAS FOUND THAT THE ACCELERATOR PEDAL FORCE REQUIRED TO OPEN A STUCK THROTTLE VALVE IS NEGLIGIBLE, AND THE THROTTLE VALVE DOES NOT STICK IN THE OPEN POSITION.THEREFORE THIS ENGINEERING ANALYSIS (EA02-015) WILL BE CLOSED AT THIS TIME.THE CLOSING OF THIS INVESTIGATION DOES NOT CONSTITUTE A FINDING BY NHTSA THAT A SAFETY-RELATED DEFECT DOES NOT EXIST.FOR A DETAILED DISCUSSION OF THE TB COMPONENT AND TESTING, PLEASE SEE THE ATTACHED REPORT.
