My car has had the wiring harness "fix" that involves shoving more insulation around the harness under the metal plate the covers most of the wiring.

I have driven around with the carpeting removed and had someone wiggle different wires and apply pressure in different places; however, I can not seem to duplicate the problem when I want to.

Has anyone else had experience with this problem? Any help would be extremely appreciated.

Thanks.

Will
