I think it might be the wire harness that runs in the steering column, but first just take the steering wheel off and see if there is any wires gounding out when you use the turn signals. Try to jiggle wires around to see if this has any effect. Does your emergency flashers work? The wires for the horn,turn signals and emergency flashers follow the steering column. You should see what looks like a ribbon with about 4? or 5? wires with a connection at the end of it. You will have to take the steering wheel off,turn signal lever off and emergency flasher switch off.There are some screws also(this happened on a 1970 chev.truck since its been about 20 years ago that this happened to me, I dont remember all the details, it probably is different on yours....the wire ribbon was brittle and it cracked grounding them).I think the wires and the turn signal thats inside the column is(all one piece,but Im not sure). Im sure I missed other things about how to dissemble.Even though this happened on a 70 Chev.truck I hope this helps in some way.
