Has anyone out there had any experience with repairing inoperative directional signals? I've followed my '59 shop manual and my fuse is good and the new flasher didn't fix it. Next they say to disconnect the wires and try a new switch..but they don't say 'turn signal' switch or 'headlight' switch. The signals worked recently and also I've just recently lost my IP lights (could be a separate issue..that headlight switch rheostat never did work real well and may have just bought the farm). Headlights, parking lights, tail lights, and brake lights all work. so, headlight switch or turn signal switch and is there a way to test for it???
