Hi all,
My 2004 tl seems to have some electrical problem. First my license plate light bulb went out, so i replaced both of them with some nice leds. Few weeks later, my front right turn marker went out, but not fully, just the light that stays on while the headlights are on, the turn signal works though. Now my left hid headlights is going purple and flickers/shuts off completely (probably ballast from what I read on other threads). Also my right license plate light bulb flickers/shuts off sometimes. I checked the fuses. Thought it might be a grounding issue, but I don't know where the ground points are to check em. Anyone got any other ideas what could it be?
