right turn signal will not switch off

[BigRedTruck]

the left one works fine but the right one seems to have a part inside the steering column broken.....does anyone know what it is called?

What you're referring to is the turn signal cam....one of it's little plastic arms along the side has broken off. The steering wheel has a nub which sticks down...

...which contacts the little plastic arms to cancel the switch. When those little arms have broken off, the switch will still work, but it just won't cancel automatically.

I have the same problem. Neither one of mine will automatically turn off. I've had to do it manually since I've owned the pick-up.

Hey Keith do you have a Pt# for cam replacement and viable source to purchase?
Thanks Tim P.

Tim: No I don't have a part number for those. However, virtually every auto parts store has a Help section with commonly-replaced items. You should be able to find a replacement cam there.
