my 69 bronco's trun signals just stay solid on and dont flash right or left. i replaced all the bulbs,grounds,flasher relay twice and still the same thing, its sending power to the bright elements but it wont flash......and here is the kicker, the parking lights work fine but the fronts go out when the headlights are turned on...:shaking: WTF!!!!!!!!!!!! any ideas? thx

Two problems -
1. won't flash - check steering column. You probably have a bad signal cam.
2. bright on signal off - check for a ground problem on the headlight - you have three wires, on is gound and it's probably bad.
