NHTSA Complaint #10463102 — 2006 CHEVROLET UPLANDER

VEHICLE HAS OCCASIONAL FLICKERING HEADLIGHTS. THERE ARE OTHER OCCASIONAL ELECTRICAL SYSTEM PROBLEMS THAT LAST FOR ONE DAY ONLY, BUT ALL DAY, AND THE NEXT DAY ARE GONE, UNTIL THEY REPEAT, BUT ONLY FOR ONE DAY, EVERY TIME. THESE ARE: THE RADIO WILL NOT WORK; THE ALARM AUDIBLE SIGNAL AND DASH INDICATOR LIGHT FOR THE PARKING BRAKE BEING ON WILL SOUND WHEN DRIVING, EVEN THOUGH PARKING BRAKE IS NOT ON; AND THE REAR HEATER FAN WILL COME ON AND STAY ON AT HIGH SPEED EVEN THOUGH IT IS SWITCHED OFF AT THE DASH. HAVE TAKEN THE VAN TO TWO DEALERS AND THEY COULD NOT DUPLICATE. TOOK VEHICLE TO DEALER SERVICE MANAGER WHILE THE REAR FAN WAS BLOWING ON ITS OWN. HE OBSERVED THE PROBLEM, BUT I HAD TO MAKE AN APPOINTMENT FOR THE NEXT WEEK, AND THEN, OF COURSE, THE FAN WAS NOT BLOWING. I NOW OPEN THE FUSE BOX UNDER THE HOOD AND PULL THE REAR HEATER BLOWER FAN FUSE WHEN THIS HAPPENS; AND REPLACE THE FUSE IN THE MORNING OF THE FOLLOWING DAY WHEN (I KNOW BY NOW) THE PROBLEM IS CORRECTED... UNTIL THE NEXT TIME IT HAPPENS AGAIN. THE ODD THING IS THAT THESE THREE PROBLEMS WILL ONLY LAST FOR ONE DAY. BUT THEY WILL LAST THE WHOLE DAY. THE PARKING BRAKE ALARM WILL SOUND SPORADICALLY AT THE START OF THE DAY, BUT WILL BE A CONSTANT RINGING WHILE BEING DRIVEN AS THE DAY GOES ON. BUT THE NEXT DAY THE PROBLEM IS GONE, UNTIL IT HAPPENS AGAIN, WEEKS OR MONTHS LATER. *JB
