There is no black wire associated with the right turn indicator unless someone has been hacking around up there.

All the following testing is done with the ignition switch on and the turn signal switch in the right turn position. Does the right turn indicator light work in the dash?? The inside indicator lights share power with the front turn indicator lights.. If the inside indicator blinks or at least comes on, then the turn signal switch is good. If the inside turn indicator doesn't work and/or there is no power on that blue wire, the turn signal switch is bad. At the connector where the steering the column harness connects to the main harness, back probe the blue (not light blue) wire.. If you have power there, you have a break in that blue wire between the connector and the bulb.. First place to check for break in continuity is the bulkhead connector behind the fuse box..
