GM MUST NOT KNOW THIS THIS HAS TO DO WITH THE ELECTRICAL WIRE HARNESS INSIDE OF THE ENGINE BLOCK FOR THE LIGHTS. FOR SOME REASON THE POWER IS OVER WRITING THE FUSES AND NOT BLOWING AND CAUSING SMALL ENGINE FIRES THAT COULD GET OUT OF CONTROL. I CAUGHT MINE IN ENOUGH TIME AND PUT IT OUT. A GUY HAS TO DO WITH THE RIGHT SIDE AND THE LEFT SIDE IN THE FUSE BOX BEING TWO SEPARATE ENTITIES OF WIRES WHICH IS 7 + 7 EQUALS 14 TO CONTROL TWO DIFFERENT SIZES. I WAS JUST WONDERING WHY AND GM NEEDS TO KNOW WHAT'S THE SENSE OF HAVING A FUSE BOX IF THE WIRES ARE GOING TO OVERRIDE THE FUSE. AND POSSIBLY CATCH FIRE OR WILL CATCH FIRE IT JUST A MATTER OF AN ACCIDENT WAITING TO HAPPEN. I'VE BEEN ON YOUTUBE AND FOUND OUT THIS IS A COMMON THING TO HAPPEN FOR CHEVY AVEO WILL THERE BE A 2004 THROUGH 2008. I'M LETTING YOU KNOW ABOUT THIS CONCERN BECAUSE I DO NOT WANT ANYBODY TO DIE FROM A CAR FIRE BECAUSE GM.MAYBE NOT KNOW ABOUT THIS THAT IT'S A BIG ISSUE AN ACCIDENT WAITING TO HAPPEN. SINCERELY [XXX] IF SOMEONE NEEDS TO REACH ME MY PHONE NUMBER IS +[XXX]. THANK YOU N.T.S.B FOR LOOKING INTO THIS.
