I have found that moisture can cause that problem you may also want to check your fuse and bulbs if you see moisture try to get it as dry as possible
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....
It could be your flasher unit. It is easy and cheap to replace. Depending on your vehicle it could be under the dash or on the fuse panel.
fuse or blub is out or blown, or wiring is bad, or the relay is bad.
If the turn signals are inoperative check the hazard switch, if the hazards don't work replace the hazard switch, the signals will start working. if the hazards are ok ,the turn signal switch may be bad.
More than likely the flasher relay is defective, replace it.
Check your fuses. Sometimes a fuse can be the cause of a seemingly difficult problem.
If the turn signals on your 1992 Acura Vigor are not working while the hazard lights function properly, it could indicate a problem with the turn signal switch, a blown fuse specific to the turn signals, or a faulty relay. Since the hazards and turn signals often share some components, the fact that the hazards work suggests the issue is localized to the turn signal circuitry. Checking the fuses and the turn signal switch would be a good starting point for troubleshooting. If those components are functioning, further investigation into wiring or connectors may be necessary.
one of them has a problem.
It contains two relays, one for hazard lights and the other for turn signals. The one for the turn signals is defective and must be replaced.
Well so far I have found that when I turn my headlamps on and switch to the high been and then use the rocker switch for the hazards, it will allow for my turn signals to start working again.
