I changed all four bulbs and the indicator in the dash is still flashing really fast

5 Answers


Did you use the factory recommended light bulbs?

Yes I did. When I turn the lights on all of the bulbs light up. But when I try to signal or step on the brake nothing lights up and the flasher still flashes fast. Do you think it could be the flasher itself?

I can't even figure out where the flasher is my guess is under the dash. I've looked in both fuse blocks and no luck


Fast flasher is due to too much current draw. There is probably a small short somewhere - a pinched wire, a corroded connector, or something, that is allowing current to flow to ground through the circuit. If your brake lights aren't working that's a clue that the problem is somewhere in the Stop/Haz circuit, which is always hot. Try pulling the Stop/Haz fuse out and see if the flashers work correctly.

Ok I will try that but I'm pretty sure the stop lights and turn signals are on the same fuse. I believe there is a short and will look for that too. Thanks for the diagram
