Thanks to everyone for their assistance but the short seems to have disappeared. When I pulled apart the column switch connector I found corrosion around some of the pins which was cleaned up with a fine wire brush and some electrical cleaner. This didn't fix it since the fuse continued to blow but it was good to get this taken care of before it became a bigger issue. However, since taking apart the actual indicator switch, moving various wires to see what I had, cleaning everything (including the female connector), putting it back together I no longer have a short. Not sure what I did and maybe it will come back but for now it seems to be sorted out. Could have been something as simple as two wires touching which was fixed by taking things apart. Kind of anticlimactic. No eureka moment.
With the assistance of this group I did learn a lot more about the wiring in these cars, found my hazard switch I didn't know I had and finally put a bulb in for the trunk light. Many thanks for every ones help.
