I feel kinda left out when y'all talk about tern signal problems. There not much original on my 66 but the turn signal switch is. Workin like new, nothing to add just wanted to brag. It will probably die next time out.

Be sure the two bumps on the came are pointing to the left when the wheel is straight ahead.  Then it should cancel evenly.   Lubricate the cam contacts and the horn contacts.  Be sure the gap between the steering wheel and the column collar is correct.

that's how I was on my first 2 mustangs...and lots of wasted money too

I replaced mine twice over the years with new Ford switch/harness that I had to repin into the existing connector block.  I can't remember why I had to do it twice, but I think it was because the new switch wouldn't cancel properly.  I messed with it, messed with it, got fed up, and replaced it, and problem solved.  Maybe I got a bad one first time out?  Maybe I made an installation error first time out?  Hard to say, this was like 23 years ago at this point.  Though I often tend to be overly harsh on my teenage self in hindsight.  I actually did some pretty damn good work in the day before you could just Goggle almost anything and find at the very least a picture, if not a Youtube video of how to do it.  I certainly made a lot of mistakes, but that's why I know so much now

I had mine out because it was hard to put into the lane changing position without going into the turn position. I lubed it with wee-dee 40 and now it sticks in the lane change position. It's a "new Ford unit" that I got back in the early 80's. What is the recommended lube?

die electric

I installed a new aftermarket wheel and it seems to stick some. I don't tighten the nut super tight. Can the horn contacts make it stick. They look flat as pancakes. hard to see in there with the wheel on?

I thought turn signals were an option on new cars.

My signal is telling you that I am going to turn or change lanes, it is not asking for permission.

I still find myself manually “auto cancelling” my turn signals after 20+ years.
It was less than 5 years ago I replaced my broken cam as a winter project.

I find it less frustrating to return it to off in the Mustang, as compared to my work truck with the electronic turn signals.

In the work truck...Light tap gives three blinks, full tap gives continuous blinks.
Sometimes I accidentally hit the stalk while adjusting the wiper speed.
Not a great combo in my book.

Bingo!

In my experience, finding a good replacement turn signal switch is very difficult. My original Ford one just wore out. Scott Drake replacement was utter trash and kept shorting out. Dennis Carpenter switch works, but cancels out too quickly and the CLICK noise is annoying. I will put up with it for now, but eventually hope to get something better.
