Hi, I have a 2000 3.2TL. My driver side turn signal light works fine when I push down the turn signal lever (which tells me the bulb is fine), however it won't come on when I turn on the headlight. Normally when the headlight is on, the turn signal lights stay on as well. Any idea what I could try myself?

 

not sure but the bulb might be a duel filament bulb. take out the bulb and check it out visually.

 

Try checkin the blinker fluid, it might be low!
