Hi All, I have a 2004 A4. Front left turn signal wont flash. All other bulbs including the side maker on the left side will flash. Hazard flashers all work except left front. No indication of a bulb out on the dash display.
What i have done so far.....
replaced bulb
replaced socket
switched head light with other side.
probed with a test light the right side, the power wire flashes fine, probed the left side wire no power going to the wire that should flash the bulb.
ran power to the left side wire and the bulb does come on.
So i would think its a break in the power wire to left side. But i would think a break in that wire would show a bulb out.
If it was a turn signal switch i dont think the left side marker light would flash.
Any help would be really appreciated.
