What owners wrote
Window switch panel on drivers door caught fire overnight while parked in garage. No problems before this event. Fuse blew stopping the electric current and the fire burnt out on its own. I discovered the damage in the morning as I was getting in the vehicle to drive to work.
I own a 2005 chevy trailblazer in dec. 2009 I filled the car with gas and the fuel gauge immediately registered empty the fuel sensor has failed it will cost $558.00 to repair. In february the speedometer registered 120 MPH while sitting still for a stop sign now the speedometer does not work. I contacted gen motors in detroit, michigan and was asked to have diagnostic done at ed bozart chevorlet.
