    Hello there drivers, my trucks left turn signal works for like 2 seconds then cuts off, and also I have no truck and trailer brakes along with it. I was told it’s under the brake pedal, could it be something else? Like the relay? I already checked the fuses and they’re all good.

    Sounds like a bad ground going on. Also, have you gone from incandescent to LED lighting by chance?

    Try replacing the flasher, for your turn signals. Also check the relays for the brake lights.
