Glad ya got it fixed, I was just about to tell you to say pi$$ on it and practice yer arm signals!!
yeah i think your right im just gonna have to wait and buy a new ignition switch but for now they are working thanks man yeah im about 8hrs away ha ha.if you were a little closer to sacramento, ca. I'd help you. It still sounds like your ignition switch is part of the problem.
On a 1970 Duster there is a turn signal fuse right side of dash around the glove box area.Not sure if a 1973 is the same.Hope this helps.If not you may need to locate a wiring schematic for your year car.
