My research to date finds that the turn signals and hazard signals are controlled by a common relay. That relay is behind the hazard relay switch. My 2002 Audi A6 has the same symptoms you describe, and I will be removing the hazard switch to get at the relay for replacement. Good luck.
1999 Audi a6 quattro, How I fix the problem when the turn signals don't blink, but hazard lights work well?
Try pushing the hazard light switch on steering column repeatedly. I had a strange problem with my hazards once and this fixed it for now. I think my problem was the signals not working though....
Make sure hazard switch is pulled all the way out May be a problem in thw steering column
If the turn signals on a car works but the hazard lights do not there may be a problem with the flasher switch. The flasher is located in the steering column, and a damaged unit can cause the lights to stop working.
Your problem very well could be the hazard switch. i have a 1994 honda civic too i found whenever i disconnected the hazard switch from the wiring harness my turn signals brake lights and of course hazards do not work. Maybe replace the hazard switch..
Flasher relay bad. This is a separate flasher relay from the one controlling the hazard lights.
Your problem is most likely the turn signal relay im having a problem similar to yours but when my signals wont work neither do my hazards
Check the fuses and it may be the flasher relay as they have 2 try turning the hazard lights on and off a few time as you relay may be stuck.
try replacing all sets of fuses for the hazard and the tail lights.
You probably have a bad turn signal flasher (or relay, as it's called in some cars)
Check the stoplight switch at the upper end of the brake pedal - common problem
Turn signal flasher?
