I went out and scratched my head after checking for voltage and continuity on my third brake light..circuit at the light is ok.. Tail lights work just fine.. Where's the danged harness run and what do I need to do to get at it. This is on a '97 850 GLT sedan. Anybody? No, no corrosion that I see, seems someone has lifted the carpet up before me near the right strut and one of the carpet plug/ties is missing. Thanks.
