Welcome to the forum, does the turn indicator on the dash work? Have you checked for voltage at any wiring circuits? There may be a multiwire connector under the dash close to steering column, for circuits going to and from the steering column. Lite blue wire carries voltage from turn/hazzard to multifunction switch. Lite green wire with white tracer carries voltage to left turn signal. Did you check for voltage and ground at the rear?
