More likely than not the Flasher Relay is defective. Replace it. check all the fuses one in the car another under the hood.
make sure all bulbs are ok
Could be turn signal flasher Check bulbs Could be a problem in steering column
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.
its difficult.
Replace the Flasher Relay.
the alternator is bad
you could but you wont be able to blink after.
Sounds like switch, and yes with a puller.
mine does that too
the hazard switch has two sets of contacts. when hazards turned on, blinkers cannot work,even if hazards dont work.for blinkers to work, hazard sw must be in off position-this reconnects blinker circuits to work normally. BUT-the contacts in the hazard sw get dirty and wont reconnect the blinkers to work
If the lights come on but just do not flash, then replace the flasher relay. If they do not come on check the bulb and fuse.
Replace the flasher relay.
Blown fuse, broken wire, no circuit, no earth. Take your pick
