    Hoping for a little help....

    Passenger side turn signal stopped working. It blinks once, cuts off and stops working. I assumed a fuse or something, checked every fuse in the bay and under dash (couldn't find a wiring diagram to figure out what fuse goes to what) and they all appear fine and when I tested with my voltmeter everything seemed to match up with the appropriate voltage. If you wiggle the stalk a little or tap that side of the stalk, it works for a bit before it just randomly decides to stop working. Based on this, I assume the stalk itself needs to be replaced. $190 new from the stealership not much of a discount anywhere else from what I see.

    The real question I have is this: When I was testing fuses/etc, I pulled the hazard fuse from under the dash. I just wanted to test to make sure that stopped the hazards from working, well not only did the hazards work still but both turn signals worked as well no issues. If I put fuse back, only the passenger side turn signals stopped working again.

    Before I replace the stalk, and since I'm no electrical expert, but that sounds like a short somewhere right? Like the circuit is being closed with the fuse but without the fuse the circuit is being completed somewhere else still? Or could a bad stalk/switch cause the circuit to still be completed? Or am I just overthinking it?

    Appreciate any feedback, thanks. (PS - All bulbs were replaced as part of this experiment, so those are out of the equation.)

    Seems your turn & hazard module is AFU. It's part of the Combination Meter, soldered & non-removable.:(
    Try this: remove the Tow fuse and the Hazard fuse, see if it still flashes via the stalk and Haz switch. Let use know what you get.
