I replaced my turn signal switch on my tilt column in my '68(not exactly a "drop in", by the way). It solved my brake light and turn signal problems. HOWEVER, the emergency flashers still do not work...unless...I depress the emergency flasher button, and activate the turn signal, either left or right.
Weird...
Also, prior to changing the turn signal switch, the horn would blow whenever it wanted to. I disconnected them. After changing the switch and re-connecting, the horn worked properly...twice...then stopped working all together.
I would get a new column wiring harness and pull it through.
I had a little current running through my column as well.. haha. I think I found the problem.
