Hey guys. Was looking into why my left front (driver side door) speaker has never worked. i took door panel off and looked at it; it looked fine to me. so i swapped it with passenger side front speaker and wouldn't you know it it works just fine. So that means theres a problem with the wiring somewhere from inside the door to the harness behind the stereo, right? the speaker works, just never works when it is plugged in to that location. any tips where to start fixing this problem? any help woud be appreciated! thanks!
