Update:in reference to the way your blinker dash light stays on when you turn headlights on...... My car did this same thing tonight,after trouble shooting I found a bulb on same side that blinker dash light was staying on. So, maybe that's why yours does this too. I know You have more issues then just this, but hopefully that's one of them,and its simple. So check ALL LIGHTS on that side. Also, I noticed when my front marker/turn signal bulb (2057) was taken out of socket,the marker/turn signal quarter panel went out completely. Seems it was dependant on the front bulb being plugged in. I found this wired. It was like it was wired in series,instead of parallel. I checked all wiring,the bulbs,(even changed em). Wiring is stock . and in good condition. I'm so interested in why this is ,that I will be downloading/studying wire diagram soon. Just thought you should know for when your figuiring out your running lights issue. Point is to check all bulbs in the circuit as they seem to affect one another .
