OK. So my turnsignals didn't work on my 68 Dart. I put in a new switch and now they still don't work correctly. If I turn the 4-ways on they work fine. If I turn the directionals on, they will blink a few (3,4,5 or so) times then they will stop. They may start back up again but just at a sporadic blink. When they stop, you can hear the blinker relay do the first "tink", but not the second "tonk" (for lack of better words). When they stop the are dark, not illuminated. What am I missing???
