Q: Turn signals not working - 1992 Mercedes-Benz 300

asked by on September 16, 2016

My turn signal indicators and hazard lights aren’t working. I’ve wiggled the signal handle but nothing happens. I’ve twiddled the relays behind the battery and the relays behind the fuse box but couldn’t get anything to work. I think it might be something electrical, because my windshield wipers are still working. Maybe it’s something inside the relay that’s not working. Do you have any ideas?
