MY 2004 GMC ENVOY HAS 90,000 MILES AND THE HEADLIGHTS AND TAIL LIGHTS KEEP FLICKERING WHEN I START IT. AND WHEN DRIVING DOWN THE ROAD THEY FLICKER. THE GAUGES ON THE DASH FOR THE CHARGING SYSTEM GOES UP AND DOWN. I HAVE HAD IT TO A CHEVY DEALER 4 TIMES KNOW, FIRST TIME THEY TOLD ME THE THROTTLE BODY NEEDED CLEANED. THEY DID IT. PICKED IT UP AND THEN IT WAS JUST AS BAD. TOOK IT BACK AND THEY RAN TEST AND SAID IT HAS TO DO WITH A PLUG FOR THE SECONDARY AIR INJECTION SYSTEM. THEY REPLACED IT. STILL DOING IT. THEY TOLD ME THERE IS NO FIX FOR THE PROBLEM KNOW THEY TELL ME MY SECONDARY AIR PUMP AIR IS BAD AND NEEDS REPLACED. THERE HAS TO BE A FIX FOR THIS PROBLEM. I CANT SPEND MONEY THAT DON'T FIX THE PROBLEM I AFRAID TO DRIVE IT AT NIGHT.GOING DOWN MY DRIVEWAY THE LIGHTS WENT ALL THE WAY OUT AND BACK ON. ANYTHING YOU CAN DO OR TELL ME WHAT I CAN DO WILL HELP.

THIS CONDITION IS CAUSED BY CORROSION OF THE RETURN AND SENDER LINES OF THE FUEL PUMP MODULE.WATER AND ROAD SALT COLLECT ON TOP OF THE FUEL PUMP LEADING TO SMALL PINHOLES APPEARING ON THE FUEL LINES.FUEL MAY LEAK AND COLLECT ON TOP OF THE MODULE AND/OR SPILL ONTO THE GROUND.THE DATA EVALUATED UNDER THIS INVESTIGATION REFLECT A RELATIVELY LOW FREQUENCY OF OCCURRENCE THAT LARGELY ARISES IN SALT BELT STATES.GM HAS EXTENDED THE WARRANTY ON THE SUBJECT COMPONENT TO TEN YEARS OR 120,000 MILES.FURTHER USE OF AGENCY RESOURCES DOES NOT APPEAR TO BE WARRANTED AT THIS TIME; ACCORDINGLY, THIS INVESTIGATION IS CLOSED.THE CLOSING OF THIS INVESTIGATION DOES NOT CONSTITUTE A FINDING BY NHTSA THAT NO SAFETY-RELATED DEFECT EXISTS.THE AGENCY RESERVES THE RIGHT TO TAKE FURTHER ACTION IF WARRANTED BY THE CIRCUMSTANCES.FOR ADDITIONAL INFORMATION SELECT DOCUMENT SEARCH.
