I've got a '66, and although the turn signals work (in that they signal the turns), they don't cancel. So I have to manually cancel every time I signal a turn.

I did a search on the forum and found an old post from 2007 that kind of addresses this:

http://forums.vintage-mustang.com/vintage-mustang-forum/550473-replacing-turn-signal-switch-wiring.html

That post, in turn, links up to an even older MM article.

After reading through that stuff, I have two questions that I hope someone can help me with. First, will a turn signal switch address the no-canceling problem? I think it will, but I want to make sure. Second, on a scale of 1 to 10, how tough is it to do this? The poster in that thread above seemed to have some problems. I know I need to get a steering wheel pull tool, but I'm assuming Autozone or someplace like that carries them.

OK, if you have the stock steering wheel, you probably need a switch. The cancelling arms tend to break over time on 64-66 switches.

I replaced the stock steering wheel with a standard 13" Grant repro. So if I replace the switch, will that fix the canceling issue? Also how hard is it to do?

If the Grant was installed without the cancelling pins, it will never cancel.

Yoma,

Common failure. Not hard to replace the switch (I'd give it a 3 on a scale of 10) buy the expensive replacement unit, not the cheap one made it china. Be sure to pull a tough nylon string through when removing the bad unit and use it as a pull string for the new unit.

I just went through that fiasco. I had installed a new import switch a while back and the signal's would never cancel. I replaced it with a new "Scott Drake" switch and it works great. As mentioned above, make sure you have the canceling pin's on your Grant.

Do I need to get the full switch? Or can I just use a turn signal cancel cam? There's nothing wrong with the turn signal itself-- it just doesn't cancel.

I have been able to get that replacement cam to work exactly once, and it was a real pain. The generic replacement switch is less than $30.
