Mitchell On Demand shows the turn signal flasher above the gas pedal clipped to a metal bracket. I couldn't find a diagram of it for you though.
Thanks for using Just Answer.
I'm doing some more research for you. If I can't find anything for you tonite, I'll check my resources at the shop tomorrow.
Here's the schematic for the turn signals. As you can see, the turn signal flasher is supposed to have a pink and a purple wire going to it. If you can't find the flasher, trace the wiring to it.
I double checked at the shop today, and the Cutlass Cierra manual, and the parts diagram all show the flasher clipped to the bracket that the gas pedal is mounted to.
Try tracing the wires like I suggested before, and let me know.
