The turn signals are going nuts -- the faster I drive the faster all four lights (two in front and two in back) flash and when I stop they act like I have the emergency flasher turned on. I assume that the flasher relay is the first thing to replace to attempt a fix. However, I'm getting mixed posts. Some say that the Prius V does not have a flasher relay that is replaceable. Can this be true? I've hunted around under the dash and under the hood and can't see what looks to be like a flasher relay. So am I looking for something that does not exist, or does it exist and I'm just not looking hard enough?
Say no more; you've got an amusingly (except when it happens to you) common gen 3 Prius issue, described further in this thread. That thread was written about gen 3 liftback, and some of the more obscure wiring details (like colors, or pin numbers on intermediate junction connectors) might be different in the v. If I remember right, v builds the flasher "relay" into the combination meter, while it's a separate box in the liftback. But I doubt the important pin numbers at the brake actuator are any different.
