You mean like pulling up the carpet and running it under the carpet, insulation and foam? While you are down there, check to see if there is much moisture from any sunroof/ windshield leaks.
Pull up the door jamb trim, first up, then back to get to the carpet, the plastic with the Saturn logo on it.
Thanks for the reply! I should have given more info. I'm actually looking to get a wire from one end of the red arrow to the other. Basically, from the footwell to where the stereo is. I can get the footwell trim piece off as well as the stereo cover, but cant figure out a way to fish a wire through.
