NHTSA Complaint #11414218 — 2010 JEEP LIBERTY

I HAVE A 2010 JEEP LIBERTY SPORT AND IT'S HEADLIGHTS CONTINUE TO GO OFF ON ME WHILE ON THE HIGHWAY AND IT'S ONLY NOTICEABLE AT NIGHT IN WHICH IS NOT SAFE. I'VE CHANGED BOTH LIGHT BULBS IN WHICH WORKED AND THEN WENT OUT WITHIN 20 MINS AGAI AT NIGHT ON THE HIGHWAY. THEN I CHANGED THE 30AMP/RELAY. THEN I CHANGED THE DIMMER SWITCH. ALL OF THIS DID NOT WORK. THEN THE DEALER CHANGED THE WINDSHIELD THAT IS LOCATED ON THE RIGHT HAND SIDE AND IT WORKED FOR ABOUT A WEEK WITH THE PASSENGER SIDE LIGHT GOING OUT BUT WORKING WHEN I SHIMMY THE CORD OF CONDUCTOR. BUT LIKE IT DID PREVIOUSLY IT'S NOW NOT JUST THE PASSENGER LIGHT AS BOTH LIGHTS ARE AGAIN NOT WORKING. AND THEY ARE STARTING TO FLICKER THEN JUST GOES OUT ALTOGETHER TO WHERE NOW THE SHIMMY IS NO LONGER EFFECTIVE. NOW I'VE DONE ALL I CAN DO ON THE ELECTRICAL REALM BUT IT SEEMS AS THOUGH EVERYTHING I'VE ATTEMPTED IS JUST TEMPORARY OR DOES NOT WORK AT ALL. WHAT IS THE PROBLEM. PLEASE HELP!
