Not sure what switch you are talking about. Do you have a picture?
The turn signal flasher will not look like a switch - just a cylinder or cube with contacts on one end.
Actually on mine, it's not. Mine is located behind the dash bezel to the right side. If you remove the radio bezel it's to the left side. It's attached there to a clip and the turn signal flasher clips in.The turn signal flasher is also in the fuse block, not under the steering column. You're thinking of the neutral safety switch.
