Having some trouble with my '70 Mach 1. Just replaced all bulbs, headlights (OEM equivalent), turn signal switch and hazard fuse. Hazards blink but turn signals do not. If I apply the brakes, hazards/signals just stay on. Doesn't matter if the headlights are on or off. Not really sure where to go from here since I replaced the switch in the steering column. Any help is appreciated.
