If you want to diagnose it www.mymopar.com has wiring diagrams for the colors to work on and a parts store circuit tester, the one w the alligator clip on one end of a wire and a light w a thin metal pointer on the other end is the one to use & is only several bucks. I'd check for fire on the particular color wires in the pull apart electrical connector(not the one for the ign but the one for the turn signals/brake lights) keeping both halves still connected & see what you find for opens. If you do purchase a TS harness ahead of time I'd plug it in the connector outside of the column before undoing the steering wheel.
