flasher doesn't flash just has constant light on
where is flasher relay located on 1991 Volkswagen Jetta
This happened to me 2 nites ago, if your hazard switch is the red bump on the top of the sterring wheel and you push it down and the lights wont flash, only stay on, there is a short in the wire. try pushing the red bump not up and down but like a flick, this should "put it back on whack".
BUY THE HAYNES MANUAL AND LOOK AT THE RELAY SCHEMATIC AND THE FUSE SET UP
