My turn signal rarely works. When it does it flashes once or twice and then it stops. I've tried contact spray which helped a little, but the turn signals still don't work right.
Turn Signal works sometimes on 2002 Volkswagen Beetle
It could be dirty or oxidized electrical connections at the turn signal switch or fuse box/wiring issue but I seem to remember reading the hazard warning light switch is the flasher unit and that it gave problems. Do the hazard warning lights work? I hope someone more familiar with VW answers your question, please let us know what you find.
