Check the bulbs. If a bulb is burned out the signal may blick quickly, or not at all. Check the flasher. Try left/right/emergency to see if any will work. If one works, but not the other, I'd guess a burned out bulb. Last but not least is the switch in the column has gotten dirty or corroded. Try some spray contact cleaner with an applicator straw right into the opening where the turn signal stalk comes out before you tear into it, which is a pain.
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.
possible bad turn signal switch in the steering column or a bad ground on your turn signals.
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 the 2005 GMC Envoys turn signal flasher. The flasher could have an intermittent issue causing the signals to not work.
Either check the fuses or change the bulb.
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
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.
they do work
