    I have a weird one

    driving down the road noticed my turn signal blinkers stopped working, no blinker light on the dash, trailer or truck, 4 way doesn’t work as well.
    then it would start working normally then stop working, it kept doing that all day yesterday and then today it just stopped working any ideas of where I should start

    2003 kenworth w900

    Sounds like you aren't getting power to the switch, or the switch itself has failed.

    I am heading to kenworth I will start by changing the switch first, I don’t know if there’s a relay because I don’t see one on the fuse panel

    Replace your flasher. Thats what happens when they go bad.

    So once I stop at the dealer the turn signal started working randomly, after changing those two parts and I started heading down the road the turn signal stopped working again

    now I am clueless

    I know it's after the fact but for future reference the flasher is located in the dash behind the ingnition switch if you remove the small rectangular dash panel bearing the Ingnition switch on the left side of the steering wheel

    I thank your fuses are in front of your clutch pedal. If so look closely at the connectors in the block.
