trying to remove the ignition from my steering column having problem getting the turn signal switch from the column

it is on the top of the steering column in the truck cab.remove battery cables. remove the lower portion of you dash.loosen the bolts on the plate that holds your column up to the dash. the column will pull down some. you may have a gear indicator tab/string that needs to be undone. remove column clamp blots all the way. the switch is on the top, it has a rod that moves and is postioned on the column. remove old switch, install new switch in th position where the old on was

The rod connects the ignition cylinder to the starter/ ignition switch on the bottom of the column.

I don't think the key and tumbler is your problem at all. The switch is down on your steering column. It's either loose and sliding around when the rod pulls, or it's wrecked. They can cause all kinds of problems. Just drop your steering column and take a look.
