Check your turn signal switch adjustment carefully. Might save you a lot of time. And make sure the wires are all plugged in completely at the connector for the switch.
I should do a permanent article on troubleshooting the 63 switches. With a black Sharpee pen or blue tape mark where the cable is adjusted on the switch so you can put it back in the same place then remove the cable. With the key on operate the switch by hand to both extremes - if both sides (and brake lights) work the switch is good. The cable needs adjusting or the mechanism under the horn button is malfunctioning. To adjust the cable put the switch on the column in the left turn signal position and the turn signal handle in the left turn signal position and tighten the cable then test.
