A few weeks back i replace my turn signal cam and switch, all work sort of. Left turn wouldn't cancel. Took apart today and found slight clearence issue, remedied it and now both turn signals cancel. Put back together and now my horn will not work. It works if i ground the horn button to my shift lever or other steel in the cab (so i know its getting connectivity to top of the wheel), but doesn't work if i ground it to the steering shaft, I know this suppose to be where the horn grounds the button, what is wrong ? im very confused now.
