1988 Silverado taillights
I'm not sure what the problem is, but my blinkers and
brake lights work if my headlights aren't on. But if I turn
my headlights on, nothing in the back works. If the
headlights are off and I turn on a turn signal they blink at
normal speed, but if I apply my foot to the brake pedal,
they blink super fast. What could be the problem?
When the blinkers blink fast, that is telling you that you have a burnt out bulb. I would change out all the bulbs. Also you may have a bad head light switch, but I would start with the bulbs, and maybe the flasher.
Correct, but they all work when the headlights are off. The blinkers only blink fast if I push the brake. I have replaced the bulbs, that wasn't the problem.
Start cleaning up ground connections first, then I would look at the headlight switch.
I fixed it. It was a ground.
Glad you found it...
I am having the same problem. Where was the ground located that you were having problems with?
