Left side marker not working
I've replaced the bulbs for both sides and
the fuse... What else could it be? I'm no
mechanic, but I can do basic things... Help?
The bulb socket itself could be bad or have a broken or corroded contact or a broken wire.
Socket is most likely the culprit, could also be a broken ground wire. Use a test light to check.
