NHTSA Complaint #10587913 — 2004 BUICK LESABRE

WHILE DRIVING APPROXIMATELY 45 MPH, SPEEDOMETER WOULD INCREASE TO AS HIGH AS 90 MPH WITH NO INCREASE FROM DRIVER. THIS HAS BEEN REPEATED SEVERAL TIMES OVER LAST YEAR OF OPERATION. ALSO GAS GAUGE INFO HAS MAXED OR BOTTOMED OUT. I CAN FIX THIS PROBLEM BY REMOVING AND REINSTALLING THE INSTRUMENT PANEL FUSE UNDER THE BACK SEAT. WHEN THIS IS DONE YOU CAN HEAR SOMETHING UNDER THE INSTRUMENT PANEL RESET. DEPENDING ON THE LOCAL TEMPERATURE I MIGHT BE ABLE TO GO UP TO 3 MONTHS BEFORE HAVING TO REPEAT THIS SEQUENCE. NOW THE A/C IS PUTTING OUT COOL AIR ON THE PASSENGER SIDE VENTS ONLY. *TR
