On a 2003 Chevy Monte Carlo LS there is a turn signal flasher unit under the dash on the driver's side that will cause the hazards and turn signals not to work properly, if it is no longer functioning. This is a plug in that has three prongs, and can easily be changed by unplugging it and plugging in a new one.
The Chevrolet Monte Carlo LS coupe has a curb weight of 3,340 pounds. General Motors produced the Monte Carlo from 1970-1988 and again from 1995-2007.
