    '79 Wagon right blinker not working

    Video demonstrating the issue: https://vid.me/ms0E

    Quick description of the problem.
    1) Right blinker indicator on the dash lights solid and doesn't blink.
    2) The front blinker light (on the front grille) comes on and holds solid when I hit the right signal stalk
    3) The the rear signal on the tail light doesn't come on with the right signal stalk
    4) Left blinker works with no problem
    5) Tail lights are all working fine

    Any ideas where I should start? Thanks in advance.

    A burned out filament is the typical cause for solid light in blinker mode.
    Change the bulb that isnt coming on.
    The right rear light that is working is a different filament in the same bulb.

    FYI, Blinker module is shared between the sides, so if one side blinks and the other doesn't, you know the blinker module is ok.

    The blinker does its thing by current going through it and heating up a strip that bends when it's hot and breaks the connection. Then it cools and connects again... Also, that's why LED conversions are more than just bulbs...

    Usually if it has a filament out it draws less current so the heating is slow. Instead of normal blinking it goes oooooonnnnnn, off, ooooooonnnnn, off, oooooonnnnn.
    Perhaps the front bulb is the wrong one as well as the rear being out, or perhaps you have the tiny indicators on top of the front fenders and it's out so that the current is low enough that the blinker doesn't heat enough to ever go off.

    The bulbs took care of it. Thanks so much y'all!

    Both bulbs were OLLLLDDDD and pretty well borked. I have no idea how the front was even lighting up.

    Glad it was a simple solution!
    The bulbs are so cheap I tend to replace them in pairs when one goes out.
