    Help: No blinkers, and the Hazard Switch stays lit solid red

    Strange thing started on the E21. For a couple of days the blinkers blinked really fast on the right side. I thought it was a bulb. A few days later the blinkers completely stopped on either side - no regular or fast blink, no arrow on the dash. The Hazard switch when activated stays lit solid red...no blinking.

    I have checked the fuses at 16B but all look good. Any thoughts and ideas would be appreciated.

    Thanks

    Sounds like you have a faulty hazard switch which controls your turn signals and your windshield wipers as well as the light on your digital clock, youíll be needing a new hazard switch or are you will need to do a hazard switch bypass so you could have working blinkers and you will also notice your windshield wipers will not work until itís fixed

    I traded out the hazard switch and the same problem exists, no blinkers and the hazard switch stays lit solid red. Have not checked the relay. Is there an easy way to check the relay? Thanks for the help

    For me, it was the wiring to the relay. If at all possible find a relay to test

    I traded out the hazard switch and no change in the issues.
    Wipers do work as normal
    Digital clock also works

    Any tips?

    See if you hear it click when you put the turn signals or press the hazard button

    That's probably relay bc the relay does the clicking.
