Hello all I have an 07 Impala LT and I've recently run into what I believe to be an electrical issue. So I have aftermarket headlights and tail lights and two weeks ago the DRL on the passenger side wasnt working, no big deal I replaced the housing under warranty. Yesterday the passenger side DRL on the headlight and on my tail light started to not work , so I switch the tail lights and plugged them in and found that the tail light in question works on the other side and also the head light. I checked all fuses in the main box and all are ok at this time. Not really sure what to do next. Anybody have any ideas?
