THE FLASHER ON THE MONTE IS UNDER THE DASH ON THE DRIVER'S SIDE. IT WILL BE NEAR THE CENTER, BUT STILL ON THE DRIVERS SIDE. under the dash on the drivers side. just left of the steering colum. Its a little black box with white lettering on it. Its about a 1"x1" box.
There is no such car as a 1989 Monte Carlo
The turn signal/hazard flasher is integrated into the flasher switch. A very common failure on these cars.
Above the radio there is a button with red triangles on it. That is where the turn signal flasher is. You have to take the dash off to get to it.
The 2001 Monte Carlo emergency flasher relay switch and the turn signal flasher relay switch are the same. The flasher relay switch simply plugs in and out.
you probably need a new turn signal flasher .
Part of the hazard warning module
Probably turn signal flasher
The turn signal flasher on a 2001 Monte Carlo is behind the hazard button on the instrument panel. You have to take out the instrument panel bezel to access it. I found this out through a Haynes repair manual for that car. I have to replace mine and did some research. The turn signals and hazard lights are both tied into the same flasher. Hope this helps.
Check for a blown fuse. If the fuse if OK, replace the Flasher Relay.

The flasher that works the front turn signals also work the rear.
In all likelihood, in a relay box, under the hood. Failing that, it ought to be in the fuse panel, inside the car.
