Either check the fuses or change the bulb.
If the 4 Ways/Hazards are disconnected then neither will work the park lights nor the turn signals.
its either the flasher or the turn signal switch
The 1990 VW Jetta turn signals will not work when the ground wire is broken or corroded. The turn signals may need the lightbulb's replaced.
If the turn signals and emergency signals don't workout sounds like an electrical problem's would suggest that you take it into the closest shop to get the problem diagnosed properly.
Well if your turn signals still work its not a short. I just fixed a pinched wire on my 96 and now my turn signals dont work. But according to a buddy of mine on Clubintegra.com there is a chance the fuse for the hazards is blown.
Check fuse Check bulbs--they are double filamented with the smaller for turn signals Replace turn signal flasher--Most common problem
my turn signals do not work in my 1992 Pontiac Firebird
they do work
It could be the turn signal bulbs, some vehicles use separate bulbs for the hazard and turn signals. It could also be a bad switch or wires for the turn signals.
if the headlights work it is bad wiring if they dont its a fuse
hazards and turn signals have separate flashers. replace flasher for turn signals
