Ever since I've had my mustang, there is something messed up with the blinkers that I havent been able to locate.

When I have no lights on, and I'm driving during the day time, the front (amber) blinkers work all the time when I turn them on, but the back only work when the brakes are not applied, when they arent applied it blinks as usual, when they are applied they turn solid.
Also, when the lights are on (parking lights) all blinkers dont work when turned on/off.
When the headlights are on, the front amber blinkers work (brakes or no brakes) but the back blinkers dont work at all whether or not the brakes are applied.

I've replaced fuses, but this doesnt seem to be the problem. Any ideas?

Thanks

These are guesses, first I would replace my flasher. Second, brake light switch located under the dash on your brake pedal may be defective. THird, your headlight switch is on the blink causing problems. Wish I could be certain, it's hard to know without seeing it.

 

my emergency flashers do the same, i dont really care bout those working all the time while im moving tho so it doesnt bother me, but i would guess the wiring is bad,

 

Check your wiring in the trunk it sounds like the turn signal and brake wiring is reversed. I just replaced my pigtails and taillights and had a similar issue until I reversed the wiring.

discussed your problem with my instructor at gtcc he said also to check and see if you have the correct bulbs you may be drawing too much amperage causing this problem let me know if this works
