    Default 89 burb turn signal

    So I am looking for a wiring schematic for my 89 V1500 5.7. My right front turn signal and indicator aren't working. I can hear the flasher and my right rear turn signal are working. So just trying to figure out which wire it is. Probably just a short or a bad ground. But wanna get this fixed.

    A short will blow a fuse, a bad ground will usually cause other lights to flash at 1/2 brilliance.
    Have you tested the front sig light?
    It is possible, that the indicator light, in the dash, is also burnt out.

    I have replaced all bulbs in the circuit with known good bulbs. No change. I believe a short or a bad ground too, but I have had bad groundz in this truck cut on all my headlights at half-brilliance and shorts cut off my fuel pump. I am ruling out the multi function switch because the flasher still gets power and the right rear light operates correctly. Heck, even my brake controller works correctly. Just my indicator lamp and right front are inoperative.
