1952 M38 with a Buick V6. I was driving along and the signal lights failed to work. Checked all lights and the 4 way flashers and brake lights didn't work either. Turns out the main harness coming down the steering column came apart, but when I hooked it back up everything works except the signal lights. The bulbs are good, replaced the flasher and they still don't work. I wanted to take apart the signal light arm on the steering column but I can't figure out how to take it apart. The column is likely out of a mid 1970's CJ with tilt steering. Any suggestions?
