    hey Folks,

    I've got a right rear turn signal out and it fast clicks when switched to the right. I have eliminated the bulb as the problem.

    I cannot find a fuse for this. I've looked in the engine compartment fuse/relay panel. I see a reference to a flasher relay but its completely missing so I think this was an option of some other model by the manufacturer. When I look under the dash, I see where I believe it may be but there is no legend for this panel. The large rectangular relay at the top/right is what clicks when the turn signal is on.

    My Chilton's manual refers to a fuse, but I can't find it. Is there one? If not I'm guessing I need to replace the flasher relay, which is supposed to look like a metal cylinder which I don't see. Attaching a pic of the under-dash fuse panel.


    I'm thinking its right in front of my face and I'm missing it.

    It usually is a lamp or the flasher that causes this problem.

    How have you "eliminated the bulb as the problem"?

    Thats been my experience too.

    I purchased a new bulb which did not work. As a sanity check, I swapped bulbs from each side. The problem remained at the location/the problem did not follow the bulb.

    front and rear? Sorry, it needs to be asked.

    Some trucks have left side, right side fuses, I don't know about yours, maybe the owner's manual will help.

    If lamps, sockets, fuses all check, flasher (as you also suspect) is all that's left.

    Did you figure out your issue?

    Hi, Pikey!
    x2 - has this been resolved? I had a '89 that the ground ribbon in the taillight circuit board corroded, causing the short that this sounds like. Could also be a break in the wire harness underneath the body.
    @columbiawifi did you check fuses in the left side dash panel? I see you checked under the hood and the pictured dist. block, but there is one more on the side of the dash when you open the drivers door.

    Good luck,
